  2. The Mark Levinson audio system of my GS 350 has no audio. It always turn on with Audio Off and there is nothing I can do to have audio. So I cannot hear any music, however I still can use my Cellphone bluetooth and have a call thru the speakers. So this is very weird. This showed up after replacing the car battery but I had audio right after battery replacement for 1 day. So suddenly it stopped working. I have read many threads on checking the fuses, rebooting the system and disconnecting the battery, I have tested all these suggestions but nothing has worked so far. I just cannot believe that just by replacing a car battery will damage the amplifier. However, I think that if the amp is damaged, why can I still have a phone call go thru the speakers ?? Any suggestions will be appreciated.
  3. Well ,,, it's possible that the problem could be in the radio head unit since that is what sends the audio signals to the amplifier. When I had low volume on a Nakiamichi system in a 2000 LS400 a long time ago, the problem was in the in-dash head unit - fixed by a Florida company. When a friend had similar low volume in a 1999 LS400, the problem was an old defective phone ECU that was grounding out and muting the audio system. Uninstalling the phone ECU solved that one. Does your RX happen to have an old Lexus phone system?
  4. I have a 1999 Lexus RX300 with the same problem ordered a different amp off the internet but still no sound what could be the problem?? Please anything would be helpful at this point
  5. Last week
  6. My suggestion is to avoid using fuel additives or randomly replacing things and to take your RX to a Lexus dealership for an evaluation. 115000 km is quite low. We have a heavier Toyota Sienna Limited van that has the same engine and transmission as your RX. It is at 95,000 miles (about 153,000 km), runs perfectly and averages from 18 to 24 miles per gallon (13.1 to 9.8 L/100km). It has been maintained according to the maintenance schedule. We live in a warmer climate where temperatures average between -10 to +10 Celsius in Winter but colder temperatures should not make much difference unless you are extensively idling the engine to warm it before driving. The spark plugs should be good to 192,000 km / 120,000 miles. I've always waited to 120,000 mles to change spark plugs per the maintenance schedule and old spark plugs always looked like new. Using premium 91 octane fuel really isn't necessary. Toyota recommends regular gasoline for the same engine in the Sienna and it runs fine on regular.
  7. Looking for some help. I have a 2017 NX200t. I have read the comments above but still can't figure out on how to get the digital speed to display? If there is a way, where can I find it in the menu? Thanks
  8. I bought this certified preowned @2013 from Lexus. I put a bottle of Liqui Moly 2007 Jectron in a 3/4 full gas tank 4 days ago, I have not seen any improvement yet but it might take more time because I have not gone through the whole tank yet. Also I always used premium octane 91 thinking its a must. I will try to check the spark plugs in a few weeks or ask a mechanic to do it for me if things does not improve.
  9. Any folks in the Northeast familiar with any auto electrical specialists I can take my RX to?
  10. Airi2010 if you are mechanically inclined I would take †he plugs out and check †hem. Mind you the back three plugs are very tricky †o get out but you will be able to do it wth the right tools. It’s possible you also may have leaky Injectors I would recommend some fuel injectors cleaner. I use Amsoil PI Additive 355mL every couple of tank full or when I go on a long trip before I would do anything, I would try this way first. By the way i burn regular gas in my 2010 Rx 350 never have used premium as recommended by Lexus. If you go to a dealer they will recommend fuel system flush and a tune up which could end up being very expensive. Are you the original owner Of this vehicle ? According to Lexus schedule maintenance replace spark plug (192,000Km)
  11. Thanks. Milage is relatively low (115000km), air filter has been replaced recently. For tune up, is this something that dealer can do or better do or need to go to shops that specialize in tune up? I have never done this before. I also tried a bottle of liqui moly last week but have not seen any improvment. based the mileage you get something must be wrong on mine
  12. OK, I been digging and digging. Been to all sorts of off-road after market and race after market vendors, and no Posi's available ... It is believed that this is the Toyota 6.7" ring gear diff ... But Toyota made lots of OEM Posi's it seems. The RX uses a differential carrier and gear selection designated -02A as shown at the bottom of the build plate in the door jam. This rear carrier and differential were available with a Posi (Torsen), all gear - no clutch, center section in RX's from 99 to 00. Then Lexus dropped the option. The same rear end was used in RAV4's, Highlanders, and RX's for many years. Any independent suspended vehicle that shows -02A can prolly use this rear end ... If you put this phrase into the search block in eBay, you will come up with a selection of used OEM LSD differential carriers. The wrecking yard interchnage number is 440-58865A Carrier Rear 2.928 Ratio Locking Fits 01-03 HIGHLANDER
  13. Mine is 96, I can relate to 95 and 97 models. There are 2 resonators near the exhaust outlets. Whoever told you that it has 4 cats doesn't know what they were talking about.
  14. Did you read the section about EV mode in your owners manual? It starts on page 139 of the 2019 Lexus ES300h owners manual which you can view online at It's probably working normally. One has to really "baby" the throttle to stay in EV mode in a non-PHEV Toyota hybrid. I've experimented with keeping my wife's Prius in EV mode as long as possible but can't after I drive out of our cul-de-sac due to very slight upward slopes in both directions and needing to go fast enough to avoid antagonizing or getting rear-ended by other drivers. A limitation of non-PHEV hybrid Toyota/Lexus vehicles sold in the North America seems to be their Ni-MH traction batteries. The same vehicles sold in Europe with lithium ion traction batteries have longer EV ranges at higher speeds. EV mode is more useful when the vehicle is just barely creeping along or not moving, e.g. entering/exiting our garage, when stopped at a traffic light or otherwise "idling" and waiting. I like how I can be waiting in line for a car wash bay on a hot summer day in silence with the hybrid system in EV mode and the interior being cooled by the all-electric A/C system. We like EV mode a lot and are leaning towards replacing our 2012 Prius with a 2021 RAV4 Prime plug-in hybrid which should become available later this year - it is supposed to go up to 40 miles at normal street/highway speeds in EV mode before the ICE kicks it. The RAV4 Prime will have a lithium ion traction battery like most PHEV's and full EV's. 40 miles is far more than my wife drives in a typical day. We're also considering the upcoming Tesla Model Y but aren't willing to pre-order without a test drive. A range increase to 320 miles was recently announced for the Model Y.
  15. But why did the fuse blow in the first Place? Seems like it might happen again if you don't identify the underlying problem?
  16. Touching on this old thread for 2 reasons i have a LS460 an Im looking to a 3ur bottom. Does anyone know if the LS460 4.6 1UR-FSE (automatic 8spd trans) AA080 <<<i think.. Will it bolt to a tundra 3UR? Secondly i may be "gifted" sorta.. A SC400 an want to drop in a 1UR-FSE 4.6
  17. We just purchased our ES300H, our first Hybrid. When the car selects EV mode on level ground there is a slight reduction in speed for the same throttle position. Almost impossible to maintain speed because when I very slightly increase throttle it kicks out of EV mode prematurely. Seems to me to be a programing algorithm glitch. Going into dealer to see if we have the latest software. Burk .
  18. We have just reached 2800 miles on our 2019 ES300H and are enjoying 44MPG over 4 fill ups. Rural driving mix of 50 MPH and 35 Mph with avg stop and go. Our Idaho elevation home is 2850ft. We have yet taken a all hwy trip. Burk
  19. Hi guys! I have had the problem of the hesitation, and wanted to sell the car, but I got a check engine light reading that said knock sensors bank 1&2, changed those, and the results were amazing, no more of that, but now I have the after sitting for a while, start, put in gear, and have to stomp pedal to the floor or pump the pedal a few times before car gets going, but once it gets going, it’s great from there, just only after sitting for a while, could this be the TPS?
  20. I can offer only standard recommendations. Try rebooting your iPhone if you haven't already. Try turning Bluetooth on your iPhone off and then back on. Verify that your iPhone has the latest iOS update. (IIRC, there was an iOS update a while back that negatively impacted Bluetooth.) Delete your iPhone from the RX in-dash system. I don't specifically know how the RX in-dash system works but some Toyota/Lexus vehicles of that vintage require separately deleting the phone for hands-free and audio streaming. Re-pair your iPhone with the RX in-dash system. If all else fails, connect your iPhone to the RX aux-in port with a cord - it's a hassle but at least you will be able to listen to audio from your phone. I did that for years on an older car that didn't have Bluetooth. By the way, can other phones stream audio to your RX over Bluetooth without problems? Particularly, something other than an iPhone?
  21. Hi, I’ve seen others post about this issue on the form but haven’t found a solution. My iPhone easily paired with the car and I can use it for hands free calling, but the audio won’t stream via BT. I can connect vis USB (although that is temperamental and will suddenly say it can’t read the device after it’s already been using it) but sometimes I just want to quickly connect to music. This is not new but I’m finally trying to get it to work. Any suggestions?
  22. So I was driving my 95 going bout 55 or 60 and all of a sudden it jerks Trac light comes on along with cel starts kinda puttering I'd call it. Then it was barely doing 40 rpms would barely go above 2 grand I still had like about another 10miles to make it home. so I thought I'd just try to push it home it's not like it died... it started acting really funny so I decided to stop looked under and seen my cats red hot wouldn't really stat and if it did it "putted" really hard decided to tow it was throwing codes for o2s and maf I changed them different codes came up for a tps changed it still putting so I started looking on the forum everybody saying those kinda symptoms are o2s or maybe an ecu tps an just a bunch of guess after beating my head on the wall for a few weeks I decided to go back check the fuses on the hood and efi2 I think is number 12 on the box was popped changed it.. fired right up like nothing ever happened so I put all the old parts back fired right up again it's bin fine every since... moral of the story check the fuses first....
  23. What look? Something like this?
  24. You have 2 cats and a resonator on the mid pipe that does double duty a a resonator/cat.
