P300 - Random Misfire
Fired up the Dodge for the first time in about a week, and the CE light came on right away. Seemed to idle a bit rough and calm itself. I used it to move a VW in the yard and then I parked it. I connected the Scanner and pull a P300 - no other codes. An Internet search yielded several possible problems with a P300, ranging from bad PCMs, misrouted plug wires, fouled plugs, blown head gaskets, bad injectors, etc.
My first thoughts are to pull the plugs and check for both carbon build-up as well as coolant leaking (note I have not yet solved the problem with the truck overheating) and then check compression on all 8 cylinders. I can double check the routing of all plug wires since I had recently replaced the intake gasket, but I'm a bit doubtful anything was knocked out of whack there as I had driven the truck for a week after the replacement was done and there didn't seem to be any problems.
Are there any other ideas/suggestions?
