Ok, sorry i was on another lexus forum... I found the problem. I accessed the ECU and removed it. Opened it and saw the notorious capacitors leaks. Cleaned the acid on the board and put back the ECU in the car. it's been 5 days now. Car runs so smoothly i just can't believe it! See thread there: http://www.clublexus.com/forums/ls-1st-and-2nd-gen-1990-2000/807090-ls400-1995-shaking-loss-power-smoke.html#post9308622 And very usefull info about the capacitor here: (luckily i did not have to replace them "for now") http://www.clublexus.com/forums/ls-1st-and-2nd-gen-1990-2000/656360-all-my-crazy-lexus-issues-solved-ecu-leaking-capacitor.html

It started with bad gas i think 3 months ago. Since then car never ran good again. I do not know about the timing belt, i will have to check on the repair records the previous owner left me. They always serviced the car very well since 1995. I will watch the video and come back to the forum tomorrow and do the test in between if i am able to :) the car is fairly low mileage (144,500) for a 1995 car i think?I got it 2 years ago with 134,000 Thanks for your help Bob!

i went to autozone 2 months ago and they told me i had 30 codes showing up, i asked to have them they would not print them for me - it had 4 cylinders issues. I went to the repair shop 5 days ago, they did not give me the codes but the parts that need replacement (see attached picture in previous reply). Since then i have decided to teach myself mechanic and will buy an OBD2 reader. I have changed my air filter this morning and also removed the MAF sensor and cleaned it with MAF sensor cleaner, car shakes less but still really struggles with power. Also, when the car was running, i removed the MAF sensor electrical plug and it shut down the car which means (according to videos i watched) that the MAF sensor is working and the repair shop wanted to charge me $500 to replace it... i will teach myself and do everything myself.

Hello, I bought my Lexus LS400 2 years ago and the dashboard lights never came on. I have read a lot of topics saying that people see them on and then they off. In my case only the squared lights are on like the picture i attached. Blinkers work. The gages lights and the computer screen are always off. http://img4.imagetitan.com/img.php?image=12_c04d6a9f-d0f5-4139-959e-dc5b74ae255e.jpg What could be the problem and the fix? Also on the front door it says the car was manifactured on 12/94, is it a 1994 or 1995? All videos or pictures i see of the LS400 1994 don't look like mine but the 1995 match. Thanks

Here is what the repair shop wanted to fix for $3,480 http://img4.imagetitan.com/img.php?image=12_3c42d6b5-d832-480a-ba5c-98c67eb4e92d.jpg

Steveuk: Thank you for your reply. Firing means that it could be the spark plugs? Thanks

Hello, First i would like to say that i am not a mechanic and that English is not my first language, so please bear with me :) 4 month ago it all started. I went to get gas at a random gas station and my LS 400 started to act out. Trac off light is constantly blinking. Engine light was already on when I bought it 2 years ago and it was certainly a glitch. Now, it happens that it blinks, sometimes when the car really runs bad. and sometimes it just stays on. So, when it acts out, here are what happens: I have very low power when i push the gas pedal There is a click sound sometimes the first minutes I drive the car coming from the engine The gears jump so does the whole car The car shakes when i am at a red light on D, less on neutral but still shakes a lot. I am starting to get some gas smell inside the car. While driving, i feel like the engine is struggling so much at times like it needs air if it was a human being. I read on this forum that it might be the spark plugs, the wires, maybe the gas filter but i a not sure at all. I really need to know what is happening and if someone can help me with some more information with the info i shared. I wish not to go to a repair shop not prepared. i love this car :) A surgeon sold it to me 2 years ago and it had been well maintained and it is a very clean car. Thank you a lot!
