It only feels like a misfire once the CEL flashes that is when the injector cuts out so then a definite misfire.
I have not checked compression as I was thinking not mechanical due to running fine until flashing CEL but will check to verify
When I replaced the head due to the crack the cylinder...
Well took the Liberty out for another drive cycle and this time it set the P0306 code with flashing MIL while under acceleration. I have always just cruised during my drive cycles but figured I would get on the throttle a little bit and it bucked once set the MIL and started flashing. So I have...
