Well this issue only happens after op temp has been reached or the jeep is sitting and idling.

Hard to start seems like its flooded, have to feather the gas peddal to keep it running, smells bad, really rich while all this is going on, seems like its not running on all cylinders. This is only a hot start issue, cold its perfect.

I have replaced, Idle control valve, EGR valve, Ignition coil, new wires, plugs dist cap and rotor.

I have ordered a MAP sensor. All vacuum lines appear good. It has a new O2 sensor.

This seems to be a common issue that I have seen recently, but with no real fix, from what I have read.

Suggestions??

Thanks,

try in tank addative for cleaning fuel injectors

 

Injectors were replaced this summer. Its running rich, I would suspect dirt injectors would cause less gas, therefore a lean condition.

Thanks,

Ok, thought the issue was a vacuum leak, was going to replace gasket, noticed motor mounts were both broken, replaced them and decided to swap the new to me injectors with the originals, after I cleaned them and installed new o rings, that was it, the number 1 injector was cracked. put old ones back in and she is happy as can be...Still have the slight manifold leak which Ill tackle later, as well as multiple other issues.

New parts are , IAC, EGR, Coil, motor mounts and MAP, all old and prob needed replacing anyhow.
