1998 lexus gs300 runs at 2800 rpm at 65 mph


At a steady 65 mph, the torque converter clutch (TCC) is engaged. When you accelerate, the ECU disengages the TCC to gain extra torque for acceleration and then re-engages TCC when speed is steady. Its kind of like having an extra gear.

My van has this issue where when I press on the accelerator the rpms drop then jump up quickly. Well most times when I slowly press on it (say stop and go traffic) the van will actually die on me and then...


VECHICLE SOUND LIKE LACK OF FUEL LEAN FUEL MIXTURE IF YOU PRESS ON ACCELERATOR ENGINE DIES,I WOULD SAY YOU HAVE STOPPED UP FUEL FILTER OR WEAK FUEL PUMP.CHECK FUEL PRESSURE FUEL PRESSURE SHOULD BE 48 - 49 PSI. FOR THE 3.3 ENGINE FUEL PRESSURE SHOULD BE 55 PSI. WITH NEW FUEL FILTER INSTALLED ALSO CLEAN FUEL INJECTORS SEE WHAT HAPPENS.

Disconnect the battery for 10 minutes reconnect the battery then start the car and put it into the D postion with your for on the brake for 30 seconds then while still holding the brake put the car the N postion for 30 seconds still holding the brake now put the car back into the D postion for 30 seconds then put the car into the PARK postion and shut it off.

My 2002 chrysler sebring lxi convertible 2.7L check engine light came on. if you accelerate in parked it revs up and then starts jumping at 4500 rpm. like it cant go higher than that. drives fine though....


That jumping at 4500 rpm is probably just your revs. limiter so you don't blow up your engine by reving the **** out of it in park. You should not have to do that for any length of time.
You need to pull the code from the computer to find out what circuit you are having problems on.
The old Chryslers used to flash the code when you cycled the key three times to the on position. For a while the new ones would display the P0XXX code on the odometer display. I don't know when they stopped doing that. But it's worth a try.

I have 2002 audit quattro TT with 180k miles. When I do a normal acceleration the car surges and rpm drop but pick back up. If I accel hard it runs fine. Also at idle at times it varies 200 rpm like a


this sounds similar to a problem i had. as the rpm went over 2000 the engine would stop for a split second and then kick back in.
after a few days looking my garage finally found the problem was a faulty air mass meter.
this cost me £200 in total to be repaired.
