Lexus SC 400 - Answered Questions & Fixed Issues

There are two large clips at the front of the seated part of the back seat. Lift from the front-center section on both driver and passenger sides. Once unseated, lol, lift up and forward. Careful not to crack the plastic around the seatbelt connectors. Other than the four bolts at the base of the lumbar section of the seat, that should do it.

YES.... with out a doubt , it will stumble , won't idle well , sputters and eats gasoline, if you have 2 and i think yours dose have, you need to make sure if its the #1-0/2 sensor before the catyl. or #2 0/2 sensor after catyl.?? , & again, if you own a computer car , get the repair manual for that vehicle from your parts house, worth every dime you spend on it.

Could be your compressor for the air conditioner they go sometimes and become tight causing overload on the motor.

When your O/D flashes, It is indicating that your main computer "ECU" is receiving an diagnostic code(s). If you can get a code reader (stop by your local Autozone - they can read your codes for free). Once you receive your codes, you do your research on the codes. If not you can post the codes here and i will see if I can advise your further. GL.

You in the ball park. I would also check the idle control valve. Also, if you have not done so, check and/or change your fuel filter. GL.

Wish I was near, I have the same car. And i know a lot about this car. I had the car for about 9 years now. I think i touch every inch of this car, except for the tranny. If you run into any problems, post them. I will be around. GL.

Hi aptaylor82, I want to help you with your question, but I need more information from you. Can you please add details in the comment box? Need the year make and model

Try a local library and check out a book with this information. It would take dozens of pages for us to tell you how to do this here. Some of the sets of books might be named: "Motor's", or 'Chilton's", or "Haynes". The repair books are year and model specific. God bless your efforts. P.S. It is possible you might find yourself needing tools that only a mechanic might have. Read the book and watch for that.

I would like at the CATS, they can get clogged, this would also cause the gas smell in the cabinet. GL

check ECM fuze , also look and make sure all plugs are pluged up reset EUC which fuse exactly( google it) alot of steps

thermostat will prob need changing, idling engine can run ok without the thermostat opening but when the engine is being used the temp will go up. but with out the thermostat opening the water will not flow round fast enough to cool down.

Change air filter and TPS (throttle position sensor). It is subject to Physical wear. (1992, Age). A dirty air filter can put the MAF sensor out of range.

First have battery checked at a Interstate battery place or equivelant. All issues point to low voltage. A shorted battery will cause the alternator not to work.

By removing the battery & the radiator the sensors sent signals to the ECM. You probably have to get the computer scanned & reset with a professional diagnostic tool. Take it to a reputable tech.

Visit the on-line store, know as reliable-store, they have the repair manuals. I'm sure you will get the solution of your problem. Best Manuals

Your almost there. Look at where the steering wheel sets and the ignition switch. There will be a bolt to remove or not. ( I haven't worked on your car), No bolt, then look to the top of the switch. There is a hole there. You have to use a small punch or screw driver and push down, when the key is in the run position, then pull the cylinder out. Either way, the key has to be in the run position.

Is the shifter stuck in park or it moves and nothing happens? If you need further help, I’m available over the phone at https://www.6ya.com/expert/oscar_403cc49e0f00cda7
