have 95 jeep grand cherokee orvis 5.2 it won't idol. I have replaced all throttle body sensors, ign coil , redone the whole top half of the motor! N it still won't iidol. Fuel pressure is good.

try to take out the idellcontrolvalve and clean it carefully,the valve is in the back of the intake,two torx screws,dont forget to undo wires first

We have already replaced that! But thank you for the help. We r clueless now!

did you clean the port or just replace it?

Cleaned and replaced.

Sounds silly but, remove the plug from cat converter. It will be loud but will relive back pressure from exhaust. That will let you know if cat is starting to clog up.
