Your throttle position sensor might be stuck on the wide open throttle setting!

Do you have any check engine codes? Is the check engine light on?

It might not be if the TPS is still in the normal range...but is just sticking open.

Sounds like your fuel filter is getting clogged up. Get that changed and it will be fixed. Should be an easy, cheap fix. Hope this helps, James Booth :))

Wish I had an answer - sounds very much like a problem I am having with my '92 LS400. I have a parts car, and have changed out the ECM, fuel pump, injectors, fuel pilter, fuel pressure regulator, ran the can with exhaust unbolted (check for clogged CATs, checked out my timing belt for slippage amoung other things, and nothing works. I have no check engine light on. Do you?

Sometimes when I press the gas pedal the acceleration isn't as powerful.it feels sluggish and has a loss of power.i can push the pedal to the floor and it moves foward slowly.other times it will work...


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.

It sounds like a fuel delivery issue so it could be many things such as low fuel pressure from the pump,clogged or partially pluged fuel filter, a malfunctioning throttle posisitioning sensor (if you have a check engine light on) or if its turbo it could be turbo lag etc.
