Gentlemen, I do not have the stopping or jerking problem. But, my car idles at an AMAZING 100-200 RPMS . I am baffled! What in the world is going on! I am planning on cleaning the throttle body one day this week to see if it fixes the problem. Should I look into changing the Ecu as well?

Tune-ups went the way of the do-do bird.

At 97k, even changing the spark plugs might be a waste of time.

Check the specific gravity and Ph of the antifreeze and the transmission fluid for a burned odor or look.

Are you saying that I should change the spark plugs?

Where is the pcv located. Does anyone have a pic or diagram depicting the location?

on the es300, it is on the right hand side, sticking out of the rear valve cover, it will have a hose that runs fgrom it to the intake maifold (the throttle body actually) i believe.

I found it thanks!!

Thank all of you for your assistance. I apologize for the use of such archaic terms as "tune-up" and "record player” . I guess I've dated myself. This is an excellent sight. I am glad that I've found it. I'll put your information to good use.

Thanks again

Hello all,

I am the new guy on the block. I just purchased a '91 LS 400 w/ 97000 mile on it for $6200. I don't have a clear vehicle history, but I've already had to replace the timing belt and water pump ($1200 at the Lexus dealership). I would like to take some preventative steps to avoid such large lump sum deposits. I am a do-it-yourselfer who enjoys working on cars though it isn't my occupation.

I've already changed the motor oil. However, the first maintenance that I would like to undertake is a tune-up. What should I include in this tune-up? And pardon my ignorance, but where in the hell are the spark plugs located.

P.S. I will never drive any other vehicle besides a lexus. I love this car :D .
