I was driving my 2001 jeep Cherokee today for around 40ish minuets and then parked an left it for about 15 minuets. When I went back to start it I ran very rough until I gave it some gas and it drove home no problems. I plugged my scanner into it and it spat out a cylinder 2 misfire code. We've had a sudden heat wave this week, it's over 80 degrees and we are still on winter gas so I'm leaning towards heat soak. I pulled the spark plugs a few weeks ago and they looked in decent shape but I have some new champion coppers to put in soon. Any thoughts on the heat soak or what else it could be?

 

I'm guessing you are correct-- heat soak.

 

It seams like it but from what I've been reading, it normally only effects the 2 inner most cylinders meaning the 3 and 4 cylinders. While mine was cylinder 2 so I'm still left wondering
