Every 10-20 starts or so the Jeep fires up very roughly. It never happens cold, and usually after a 5-15 minute stop for an errand. Runs really rough for a minute or two, and does not respond to tapping the pedal.
IAC valve has been removed and cleaned.
Connection to IAC has been cleaned with electric cleaner.
New plugs.
Intake cleaned.
Two instances of check engine light from this behavior: #3 misfire, and then a generic misfire code later.
Dealer sucked a can of M44 top end cleaner through the system.
Have run a bottle of Lucas with each tank since.
Running out of trial and error money right now so I'm hoping one of you folks has some experience to share. My wife won't drive it until this is resolved and she's missing what I traded for the Jeep over this as well.
Thanks for the help.
