I've got a 1998 Jeep Grand Cherokee with a 4.0...I noticed Saturday while at The Flats that it was having an idle issue after warm starting it while wheeling. Say I was parked for 1-10 minutes and went back into the Jeep and started it, the Jeep would idle very rough. It didn't do it every single time I started it but it did it quite often. It sounded like it was under water to be honest. One kick of the throttle and it would clear itself out and it wouldn't hesitate when I gave it gas either. If I let it sit there and run while idling like that it would eventually clear itself out after 20-30 seconds.
It's an intermittent issue. It doesn't always do it but revving it up will clear it out every time it begins to idle like that and then it will go back to idling like normal although it always has had a sort of rough idle. The Jeep has new Champion plugs gapped at 0.035", new spark plug wires, new distributor cap & rotor button, new TPS, new IACV. It does NOT have a check engine light or stored codes. A friend of mine said that it could possibly be an injector bleeding fuel whenever the Jeep is not running and that's causing it to act like it's flooded somewhat?! I just figured I would ask a more experienced group before I start throwing parts at it. Thanks for the help guys!
