1990LS400

I've never understood how K&N could stay in business with the problems their products cause. The MAF is an expensive and sensitive item - I wouldn't do anything to endanger it. Aftermarket filters will not do much if anything at all to improve performance or fuel economy on a modern car like your GS430. Heck, I just got back from a 600 mile Interstate highway road trip on which my 2000 LS400 V8 averaged 26.1 mpg on OEM filters - cruise control was set on about 73 mph to get a true speed of 70 mph per my GPS and phone. The overall average might have been over 27 mpg if the trip had not included a little city street driving. Your GS430 might do as well if driven gently and working properly. Less than 20 mpg is about the norm when your car is driven mainly on city surface streets. The revised EPA fuel economy estimates for the 2006 GS430 are 16 mpg city; 23 mpg highway; 19 mpg combined. If your MAF has been damaged, you may need professional help to get it fixed or replaced.

Yes. You will used to it. You must have just acquired the car.

It seems a little odd that a 2009 has already had two owners but that may not mean that there is a problem with the car. Buy it if it is exactly what you want in color, equipment and condition. Been there, done that. It may just be me but I will never buy another vehicle that doesn't have self leveling HID or LED headlights - not just for the better lighting but also that bulbs almost never have to be replaced. My 2000 LS400 is still on the original HID bulbs. You might check to see if the car has HID if that is also important to you.

What is your concept of "fully loaded"? Does it have the optional panoramic roof, HID headlights with AFS and rear sunshade?

13 mpg seems bizarrely low for an RXh.. Does your RXh have remote start and, if so, are you using it? Are you running the engine for extended periods to warm the engine and/or interior? I wouldn't think that driving a slower speeds on snow should hurt fuel economy that much since hybrids usually excel at lower speeds. Is your RXh front wheel drive or all wheel drive. If it is all-wheel-drive, the rear wheel traction motor turning on more often while driving on snow may be a factor contributing to worse fuel economy. You might try manually calculating your gas mileage over a number of tank fill-ups if you are instead relying on your trip computer. The trip computer may not always be accurate. AZ is too hot in summer - I don't care if is a "dry heat" - it's too damned hot. Last time I was in the Phoenix metro was in July when it was something like 110 degrees every day. I'll take humid Florida any day as long as I don't fall into a sink hole.

How cold has it been there? The engine in our Prius v wagon runs more in cold weather. In summer it will run it in EV mode all the way out of the cul-de-sac but in cold weather the engine starts before I'm out of my driveway. Are you allowing for colder temperatures when you check your tires? Last week I added 5 or 6 more psi to the tires in our cars than shown on the door jam sticker while the cars were parked in our 50 degree garage to allow for outside temperatures down to about zero. Since it could be as low as -10 tomorrow morning I should be adding even more pressure. Tires gain or lose approximately 1 psi for every 10 degrees of temperature change. If tire pressures are not monitored closely when there are wide temperature swings, tires can become dangerously low on pressure and, of course, diminish fuel economy. Yes, drain and fill unless your maintenance manual says otherwise. Winter sucks!

Sometimes questions fall through the cracks. Check the diagrams on Sewell Lexus site. "Paste" has been deactivated on this forum so I have pasted the relevant URL into the attached text document. Be sure to register with your forum member name on Sewell's website if you order parts to get significant discounts. It is not necessary to register to see the diagrams and retail prices of parts. If you register, you will see "club prices" which are often substantially under retail and their regular on-line prices. Sewell Lexus parts.txt

The CD recording feature has apparently been deleted since it is described in the owners manual for the 2009 LX570 but not in the owners manual for the 2011 LX570. I assume the feature was considered obsolete. Consider doing what I did and "burn" your CD music collection to a smart phone using Windows Media Player or a similar program. I also copied most of my CD collection to USB flash memory but I rarely use it and prefer to stream wirelessly from my phone via Bluetooth. But I don't play my personal music collection all that much any more. I stream most of the music I listen to from the Internet - mainly from Pandora to which I subscribe to get it advertising free and occasionally from Slacker and iHeart Radio. I don't even listen to broadcast radio much anymore. All the radio stations in town and 70,000 around the world are on the free tunein radio service on the Internet. You don't need Lexus Enform to steam audio from the Internet. Just connect your smart phone wireless through Bluetooth or plug it in to your 3.5mm aux-in port and control the streaming from your phone - helps to have a phone holder or cradle mounted on the dash. Kuda has some very nice leather mount consoles for the LX570 is you want a convenient place to mount a phone holder or charging cradle: www.kudausa.com I've had phone charging cradles mounted on a Kuda console in my 2000 LS400 for about 10 years. If you want a simple phone holder, I highly recommend the iOttie Easy Flex 2. We have one in our 2012 Prius wagon and it sticks like iron - even to a textured dash and does not do any damage.

The switch panel - see the arrow in the attached diagram - will have to be removed to fix this issue and to determine if anything is broken that has to be replaced. Specialized non-scarring trim removal tools are best to use to disassemble the center console which is usually held in place by friction fittings and occasionally be a few well hidden screws. I sometimes use regular screwdrivers and a putty knife with electrical tape applied to the blades to keep from damaging trim. One must be very careful when prying console components out using gentle but firm pressure and working around the edges of panels so that excess pressure is not put on a part of a panel. . From my fairly limited experience, I have come to the conclusion that center consoles in vehicles made by Toyota share the same types of fittings and are held together about the same way. I know that I can remove everything in the center stack - wood panel around gear shift, radio, A/C and heat controls, center vents - in between 5 and 10 minutes but I've had lots of practice and have the right tools. I think you have to at least pry out the wood panel around the gear shift to see it that allows you to pry out the switch panel. It may be necessary to pry out the radio/navigation/HVAC/vent assembly to get the switch panel to come out.

My recommendation is to follow the diagnostic procedures for your specific car. I have them for my LS but I don't have them for your ES350. And while I have the diagnostic procedures for my car, I do not have all the diagnostic tools needed to follow them. The diagnostic procedures are available at techinfo.Toyota.com Maybe someone else will chime in to help you. The sensors are a little pricey so you don't want to replace them needlessly and still be left with the problem.

I'm with gbhrps. A two or three year old used car is the best way to go if you aren't itching for a brand new car. If you are patient and a little flexible on price, I think you can get a much newer, low mileage ES350 for at or for a little more than ore than $18,000 particularly if you can find one being sold privately. My 2000 LS400 is a good example. I bought it in 2003 when it was about 39 months old when it had about 38,000 miles on it. It was still like new. It originally listed for over $60,000. I paid right at half its original list price and might have tried to get an even better price had it not been the first day it was for sale and exactly what I was looking for. I'm still driving it at its current 176,000 miles.

You can't expect a Lexus dealer to diagnose a problem over the phone. A code 51 and the misfiring might indicate a failed 02 sensor but it could be something else. But experimenting by replacing 02 sensors and other parts can cost far more in the long run than taking your car to a knowledgeable mechanic. Lexus dealers are often not the only game in town. In my 24 years of driving Lexus cars, I've mainly used independent repair shops that specialize in repairing Lexus cars.

Hmmm ... not sure what previous poster "Henryk" thinks he is contributing. OK ... first of all, have you owned this car for a while and this issue just started happening or did you just buy the car and aren't yet familiar with how everything works. When you say "entire dash", do you mean just the instrument cluster or "everything" including all the lights in the center stack (e.g. HVAC controls, radio)? Have you tried adjusting the dash light rheostat switch? Verify that it is not turned all the way down. If your 99 ES is like my 00 LS, there is a separate rheostat setting for the dash lights for when the headlights are on and when they are off. Is the problem the same when the headlight switch is in the "Auto" position and when it is backed off one click to the manual headlights on position? Also verify that nothing is obstructing the light sensor on the upper left corner of the dash near where the dash meets the windshield. Normally, though, if the sensor is obstructed the headlights would be on all the time - night or day - when the headlight switch is in the Auto position.

Yes, go ahead and add 91 octane to your tank and use only 91 in the future. The slight difference in cost isn't worth the trouble.

The first thing I would do would be to swap the wheels ... RF to LF, LF to RF, RR to LR, LR to RR. If it still pulls to the right the same as before, it means that you have eliminated wheels and tires from being the cause of the problem.

"turning under strong acceleration"? Yes, if you turn sharply, gun the gas pedal to the extent that the tires slip on the pavement, traction control will intervene on vehicles made by Toyota and other car makers and will automatically reduce the throttle until slippage is eliminated. Is this your first vehicle with traction control? Yes, turn traction control off if you drive like that.

The procedure for removing the 2nd row seats from a Sienna is almost identical to the one for an Odyssey except that the Sienna has a safety lock that must be opened by pulling a strap under the seat: Slide the seat forward/fold the seat back down/tip the entire seat forward/pull the release strap/lift the seat out. It can be done in maybe 30 seconds per seat. That the release strap has to be pulled is not obvious to someone not familiar with how it's done. It looks like it is going to be a FWD Sienna Limited for us. I found out directly from Toyota that HID or LED headlights are not going to be available on the 2014 Highlander Hybrid Limited (the Toyota dealer was wrong ... no surprise) and that the Pre-Collision System (PCS) and adaptive cruise control is for some unexplained reason available on the FWD but not on the AWD Sienna Limited. My guess is that the reason is "price point". An AWD Sienna Limited with those features would likely push $60K. By juggling features, Toyota keeps the prices of the most expensive FWD and AWD Siennas just barely under $50K.

Been there, done that. 100W bulb exploded causing quite a mess and a lot of cleanup. Maybe try normal wattage Sylvania Xtravision bulbs.

"Large and cumbersome" is what I think of the GX. It is not that it is all that large - it just seems larger than it really is. I was going to suggest a Toyota Sienna AWD but the term "minivan" seems to disgust many people. The Sienna is certainly not "mini" - it is a large vehicle. The top Sienna Limited is like the Lexus of vans. Being a Toyota, almost all the controls will seem familiar from your Lexus. The Sienna Limited is available with HID headlights, Adaptive Cruise Control and Pre-Collision System with a price not much different than a GX. We are on the waiting list for a 2014 Toyota Highlander Hybrid Limited with Adaptive Cruise and PCS. The dealer says it is going to have HID but can't show me any documentation that confirms that it does. HID (or LED) headlights are a must - not going back to halogen headlights after all these years. My wife wants to get another hybrid (she drives a Prius v wagon) but I would rather have a fully loaded all-wheel drive Sienna. The only problem with the Sienna for us is that it is LONG - would just barely fit in our garage. But I sure like them - rented one a few years back for vacation use and loved it's comfort and capacity. It drove nicely too - very car like and handled well. I also like the Honda Odyssey Touring models (HID is available on them and I think they handle a little better) but I would rather stick with Toyota reliability ... we had lots of Hondas before our Toyota/Lexus cars and don't have fond memories of those Honda days although I know Honda has gotten a lot more reliable. If I was still launching boats from a boat ramp, I would want an all wheel drive vehicle.

Have you looked for it? The diagrams and photos that were displayed when I searched with Google for "1993 SC400 ODB photo" seemed to show where the two ports are - one in the engine compartment per the description you found and the other low by the kick panel in the driver side foot well.

Google "1993 SC400 ODB photo" and you will get photos and diagrams of where it is - apparently near the fuse box under the dash on the driver side and perhaps behind the carpet.

OEM HID components including ballasts usually last for the life of a vehicle. My 2000 LS400 is still on the factory installed HID bulbs and all the rest of the original headlight components. Aftermarket HID kits vary widely in quality with some of them being complete junk. I'm not a fan of aftermarket HID although they usually work much better and are less dangerous to other drivers when installed on a vehicle with projector headlights like your GX has. People seem to get the best results from aftermarket HID kits if they are powered from the battery or the engine compartment fuse box using a relay rather than from the headlight connectors. How is your HID kit powered?

Fess up, Billy. We know you took this photo while driving one of your LS400's.
