This is for damn sure a mystery that I'm eagerly awaiting to see resolved. Fingers crossed they find it. Curious, though.....if they continue to diagnose it into the 1k price, will you just give up or have them throw a new engine in it?Update - Leak-down came in with less then 1% loss - so no problems there. Got PCM from flashmasters, same cyl1 and Cyl2 misfire at idle only. I have no idea what else could possibly cause this. SO, decided to bite the bullet and take it to a "highly rated" dealer, Garavel Jeep in Westport CT with issue quickly going from $165 diagnostic to $500 with no answers as of yet. Will update if dealer is able to solve the issue
Me, I'd try to negotiate absorbing some of the cost of diagnosis into that new engine.
