Nice.... hope the ride is also nice....

No photo.... now the check light is coming on and going off ...... light off for 2 days comes back on .... kind of intermittent but with a prolonged duration

Do you have pictures of where exactly this sensor is located? i searched google but there are no images for 98 model...

Changing the ECU?! ..... also Craig this error code is eating up my fuel mileage again what bothers me more is the sluggish gear shift, when shifting from 2nd to 3rd it gives a good amount of jerk, but then again for this jerk i have a feeling that my transmission mounts must have been transformed into solid rocks rather than acting as a shock absorber

Hi Finally i managed to get the OBD II device (ELM 327), i am having a check engine light on this is what i am able to pull up with the device I just wonder what in the world is turbine speed sensor!

Michelin Primacy mxv4.... these are good and comfortable

Hi everyone Finally i managed to save some money and went to replace my old tyres with Pirelli P7 225/60 R15 H And what a difference! amazing rubber, no tyre noise at all on the road all you can hear is noise from the engine and the outside air noise, great grip at corners Overall ride quality on a 98 LS 400 amazing, highly recommended

great improvement i must say.... now i am getting total 360 miles in tank full.. good job

Well i am not seeing much economy gain, it should give atleast 350 Miles in a tank full..... regardless i noticed two big things 1.) Check engine light gone; occasionally it comes on but most of the time after cleaning MAF its gone for good 2.) Smoothness!, gear shift is much smooth and overall acceleration is smooth noticeable difference! Next stop oxygen sensor replacement

Hi Angel Welcome to the forum For the fuses you have two boxes one fuse box is under the steering wheel and the second one is under the hood... best is use a crow plier and plug and unplug all the fuses and check accordingly all the fuses just to be sure... if you have even a 1% doubt on any of the fuse just replace Now power windows and your blinkers not working these are two separate issues, power windows are moved up and down by a motor ... blinkers are not working most probably fuse if fuse are fine then most probably the combination switch is not functioning properly Check for diagnostic codes also, they help a lot

Hello everyone I recently encouraged and pushed myself from laziness that i have to clean that MAF sensor although there is nothing wrong in my car except it is giving me now really poor economy Anyway i started to take it out ... and these were the problems which i faced 1.) I did not knew how to unlock the connector anyway i managed and inserted one flat screwdriver and pushed with the clip pressed and it came out 2.) Now the connector being disconnected taking out the MAF unit, there are 4 screws two "+" screws are there and two 10 mm hexagonal screws, 3.) Tools: unfortunately i only had one flat "-" screwdriver with me i managed to unbolt the + screws from MAF sensor, now how to unbolt the hex 10 mm screws? i asked the neighbor and ofcourse with my all time bad luck he had only one big multipurpose wrench, i tried anyhow with that i was able to open one screw but the other one which is near to the air filter wont budge since there is no space due to ABS actuator box sitting there, there is no space to turn the wrench! i gave up put everything back on and went outside to take a break and to buy some tools 4.) I went to store and bought some wrenches, + screwedrivers etc 5.) I came back and started again this time it was easy to take the sensor out, to my surprise its a big sensor with a good amount of engineering being done on the shape of it it is more of a small jet engine inspiration Now a closer look at the filaments inside the housing 6.) Cleaning: How to do it? i browsed through many forums and videos everyone using a cleaning spray dedicated only for a MAF sensor which i honestly believe is just a marketing strategy to lure people to buy their product eg CRC cleaner etc......... anyway obviously i did not had that spray now what to do... After some research i found out that the chemical composition of the CRC cleaner was mainly petroleum, and since petrol in the form of spray is a good cleaning agent and it evaporates into the air, similarly i thought i can use alchohol or spirit (methanol) to clean this, i had a deodorant (contains isopropyl, methanol) with me at my home and gave it a go sprayed right into its face Result was good it cleaned the filaments were looking bright and shine only thing missing was that long nozzle so that you have more reach, if had just had a straw in my home i would have made that long nozzle I think even if you have spirit which is used for medical purposes (to clean wounds) you can use that also after all purpose is to clean the dirt without water and without damaging those delicate filaments. I installed the MAF sensor back just some time before, lets see whether it gives me any good result (improving the gas mileage) or not

I was in the same situation the car died, you can refer to my post... If the starter is not engaging may be it gave up or may be the security system, i seriously doubt that water can reach in that cave where the starter is placed, the biggest problem you are going to face here that every mechanic will say one thing "Replace the starter motor" Used starter you will get for 200 dhs from sharjah make sure you take the old with you when you are hunting for the used one just to match in case brand new for ~1350 dhs (from Al Amani spare parts) or ~1250 dhs (from popular auto spare parts) Good luck and keep us posted

Yeah the double tank issue...... i was also offered the same advice that to replace my whole radiator to double core/double tank... what my mechanic told at the shade tree that the your current radiator is only 24 mm width of the core.... double core it will be increased to 42mm.. Moe did you find any advantage with a big radiator and how much did you paid? does your car have two fans in the front?

Well to be honest it happened to me while i was driving so i cannot say about any kind of noise... although my AC was giving chilled air even after the radiator leak AC was chilled did you find out where the leak is coming from?

Hi Billy Refer to attached, taken from toyodiy.com 87-01 MIRROR diagram, 09_1997 LEXUS LS400.pdf 2000 Lexus LS 400- Outside mirror.pdf

apparently the manual which i downloaded from this forum for 98-2000 LS 400 says 5W 30..

hmmmm so it is same same everywhere, leave the car, we will check and will get back to you ... i am amazed by the quality of the build in these cars not to mentioning anybody can easily repair them

Oil... i am using normal shell engine oil 15W 50...

are you serious it can play FLAC? brilliant

hmmm i heard kenwood ddx470 is a good direct replacement in LS400 which connects the amp and the sub... only downside will be the original look of the car will be gone but on the other hand it is always nice to have a good LCD display...

I was also trying to say what billy said, but hesitated lol

Sadala, if it is not firing up then its probably mechanical problem, and since you have the master key it is unlikely that you will get stuck by the electronics... do you see a check engine light on your dashboard, can you manage a code reader from somewhere and try to pull out the diagnostic codes?

It appears that the starter motor is shut off by the car security system... could you please post a picture of the key which you currently have? also you are saying two things at a time, select an option from below 1.) The car is cranking but not firing up 2.) The car is super silent even when you turn the key to ignition To fix the car security system, simply lock the doors from the button on the key and then unlock the doors, this should probably fix it 1998 LS400 key programming.pdf

Well even i cannot say with full confidence what might be the full options... since these cars came to US only maybe other experts here would tell what includes in the full options/option 1 You changed the music system... hmmm with what make? are you able to make use of the amp already provided? Auto levelling HID? did LS400 came with HID from the factory? i just wonder... mine is from west virginia and have normal bulbs in the headlight, sun roof, leather seats and massage seats

mine is already driven 236,000 miles.... and my guess would be that nothing got replaced in the engine bay till these years by the previous owners.. regardless i will try to replace the main parts soon
