A failing brain box can cause the vehicle to run very rich or very lean, poor power, hesitation, bad gas mileage, lots of smoke out the tailpipe etc. What makes you think it is the ecm (brainbox)? i notice its a lexus. We see a lot of those brains. If you need the brainbox please call us at 888-672-4816 to TEST your original free of charge then replace or rebuild if need be. We also have them available for immediate delivery. Tell them Tim from Fixya.com sent you for a free lifetime warranty. Please advise. -Regards, -Tim

    i just noticed your vehicle is an ls400. your brainbox, aka ecu is most likely bad. I personally have rebuilt hundreds if not thousands of these computers and the sc300 400 style for similar failures. Dont buy a used one as it will most likely have the exact same issue and no one builds them better then us so i would call for sure, especially if yours is 1991 to 2001 888-672-4816 -Tim

Why do you think there is fuel in the oil? Does it smell like it? Or is the dipstick level climbing? Tell us more about the problem and what you have already tried/done. When was the car last fully serviced? Poor maintenance is no excuse for poor running.

What is wrong with My Lexus LS 400, reverse gear was burnt but was fixed. After repairs it started consuming much fuel, raw fuel comes out of the exhaust, the oil was changed it was mixed with Fuel.


You really need this fixed fast for if you have raw fuel coming from your exhaust your catalytic converters must not be working. If they were working they would be running a extremely high temperatures and be a fire hazard.
You most likely have damaged exhaust valves causing this problem, a compression test will confirm if this is the case. The other possible causes are bad injectors, coils, spark plugs and ignition timing.

Can you put transmission fluid in gas tank ls400


Serously do not do that. Your car will not run as gasoline never mixes with oil in a non diesel engine.

Either fuel is dripping into cylinder after the ign is turned off or you have carbon built up on the valves or plugs and it it hot and ignites the air fuel mix when you turn ign off pull spark plugs and inspect.

Makes a knocking noise when starts and then goes away.


if this engine has hydraulic valve lifters, then it could be a weak hydraulic lifter that pumps up once the oil warms up. Hopefully you dont have low oil pressure. Does the oil light stay on for a while after you start the engine. If it does that could cause your engine to knock

Need to get that checked out immediately. Coolant in your oil will ruin the engine in a hurry.

My 1990 Lexus LS 400 stalls unexpedly (at any speed).When put in neutral, it starts up and runs fine for a few minutes then stalls again. Why?


Your fuel pump or fuel pressure regulator are not supplying constant fuel pressure. Too much or too little is causing it to kill. You can pull the vacuum line from the regulaor and check for gas. If there is none, you need a pump, it is weak.
