Misfire Cylinder 2, goes away when car warms up

Hi all,

I have a 2006 Nissan Murano with 160k miles. I live in Idaho so it's a bit chilly at times, and recently my car will misfire in the morning when I start it up. When it gets up to operating temperature, however, the misfire will go away. I did some digging, found it was a P0302 code. I then swapped cylinder 2's coil with cylinder 6, and upon doing so the misfire code followed to cylinder 6! So my natural inclination is that it's a bad coil, but why does it go away when the car gets up to operating temperature? Any thoughts would be appreciated! Thanks all!

heat causes things to expand. It also drives away moisture. The coil is probably is probably borderline working, possible cracked.


I’ve had this happen to me so many times!
