If u did mopar coil and wires u would think that might be it. Hate to say for sure. These jeeps are so finicky with parts it’s ridiculous. I heard long ago that the ecm takes a little time to LEARN a new part when it has been replaced. I know now that to be true. I replaced an off brand purge valve with a mopar brand which too about 2 weeks before it actually cured my issue. Sounds crazy but it’s true. Having said that I did put NGK iridium plugs in my 07 on my last change and the Jeep loves them. Increased mileage and very smooth idle. It seems to me that mopar parts have just a little different voltage. Crazy right? You will get er ol buddy!
