Thank You for stopping by... I need some help with my vehicle. Purchased a used 92 eclipse gs. I recently changed the air filter, spark plugs, wire set, throttle body cleaned, new pcv valve, new cat, has new timing belt and muffler. I also tightened the tension on the throttle body wire since it was very difficult to accelerate.

MY Problem:

The car drives fine yet it tries to stall on me. When in drive at times, not consistent, when i let off the accelerator and the rpm drop down in the 1000 range my engine begins to vibrate shake like it wants to die and the check engine light goes on. No change if i put in neutral and have to rev the vehicle to around 2500 to 3000 rpms and then she stops shaking and the check engine light goes off. When i put it in drive she shakes rattles until my rpms get to the above range and then she takes off like nothing happened.

RPM at idle around 1000 and while in drive 500-600.

Any suggestions will be greatly appreciated and thanks for the help in advance. :57:

This used to happen to me in my 97 gst...

There is a small plug that goes into the alternator (located at the bottom of the alternator) check to see if its loose or unplugged!

This might or might not be the problem.....hope this helps :)

idk if alternator would make it shake. but you should idle at 700 in drive... what all did you do to the throttle body? your spring might be closing it to much and not getting any air to idle explaining why its fine with your foot on the gas.

Just cleaned the throttle body out thats it....yet she dies when in idle or drive if the rpms dip below 2000 :)

check your MAF

is there a wire or somthing pinched between the throttle bodyand the manifold it sounds like you have a gargantuan vacuum leak I would pull that part back apart and inspect it how about the IAC is it seated completely?
