1992 Lexus LS400 QuestionsRefine by vehicle
All major work under the hood has been done and battery replaced. Car has been sitting a while. Replaced fuel pump and filter tune up oil change and all
I have tried everything.
Did test, did tuneup.
Replaced a lot of sensors.
92 LS 400 - Just started today, at any speed from idle/stopped to highway speeds, car won't accelerate and bogs down unless I floor it. When I do floor it, it jerks like it just suddenly got a blast of fuel and leaps forward. Then it's fine for a little while before it repeats the same. Almost all stops or low speeds cause it to happen though. Only flooring it will force it to accelerate. Anyone have an idea what might be causing this?
could it be the mass air flow sensor?
It's going through a lot of power steering, but it's not leaking on the ground and I can't find the leak.
So much smoke comes out of the exhaust, that when I leave the area it looks like there was a fire in the area. It happens when I start the car or when I accelerate.
it stalled when i tried to restart it it turned over but wouldnt start the engine got wet a little
changed the engine and harness what all do we need to check when replacing engine for as electrical
The seat belt warning light does not come when I start the car and belt no fastened. The warning light is visable when the key is turn on (not started)
i had both rear os replaced, do i need to replace front os too
after replacing brakes and bleeding car does fine,more I drive there's a drag on car,have to push accelerator harder to have it keep up the speed.And the engine is getting hot.Not the temp gauge,just excessive heat coming from motor into car.
Also in AM car won't go when temp gauge in close to bottom of gauge,once it starts warming up makes it easier to go in gear(drive)this only started when what I thought was brakes locking on me,that was reason for replacement.When start in morn after temp warm up runs good,then slowly downhill from there,to the point afraid I'm pushing it to go that I'm going to break something if not get stuck somewhere.
Please help!! I think it's a simple problem.Could the proportioning valve make the brakes do this??
Thanks .one heck of a headache
I changed the spark plugs, it still starting like it want to cut off.
