1996 Jeep Grand Cherokee Question: won't idle



, Fremont, CA, March 29, 2011, 23:18

My jeep will only start when the gas pedal is held wide open and stalls after I let off the gas pedal. I replaced the air idle control valve recently. Whats next? the TPS?
Can I check the old one?

    I wouldn't say the TPS. My thinking is that when you give it a WOT (wide open throttle) that it shuts off any fuel supply. This is typical of electronic fuel pump operated vehicles.

    It could be that you are still getting no air into the engine, on the other hand you could be getting too much air. Check for any vacuum leaks or an air intake leak. Check base fuel pressure.
