Well I got a weird one this week. Truck decided to throw a CEL, So I did some investigation and was able to reproduce the Misfire code.
If I get up to Speed dosent matter if it WOT or Slow upshifts. If I let the truck coast for a long time the Cyl 4 Misfire Code pops up.
Truck Runs perfect and everything is new since I did a cam swap.
Will do the basics this weekend, Swap the coil pack, Put in new plugs, Check my headers for leaks, do a compression test ect.
I just hope its not a bad Valve Guide, That would suck having to do that again.
Just looking to see if Anyone ever got a weird CEL like this and what was the cause of it ?
