P0301 Cylinder 1 misfire

Ok. so my truck is only throwing the code for cylinder one and i cant figure out why. all new plugs and the coils are seated properly. im not noticing any rough idles or anything of the sort but it seems to be robbing MPG's. I've kinda hit a wall on this one. Does anyone have any suggestions or similar experience?

Re: P0301 Cylinder 1 misfire

There have been many comments that Cyc. 1 is the easiest to misseat the coil pack on. It maybe worth another look see. Maybe swap #1 and #2 coils over see if it moves the miss to # 2. Good luck

I didn't know you could just swap coil packs. It's worth a try. If the misfire does switch to cyl 2 would that mean I have a bad coil pack?

Re: P0301 Cylinder 1 misfire

Re: P0301 Cylinder 1 misfire

I mine had a miss fire code, and was idling rough too. There is a service bulliten about the spings on the exhaust valve springs and it is covered to a 100,000 miles, bad thing was my truck had 130,000, it is a 2005. But don't let a dealer sell you a head to fix it, get a valve job done got 135. The deler charged me over 1800 dollars to take it apart and putnit back together, and when they could not fix it, they said it was an exhaust valve leaking, but i told them i wanted the head and had it fixed myself, itr was a intake valve sticking open.
