It all started out as a rough idle while cold, good warm. then started knocking cold, good warm. then it rapidly turned into a rough idle with an occasional knock and white smoke. this ONLY happens at idle, and it now happens most of the time but not all the time. this leads me to believe it's an electrical issue.
so I've got fresh filters, fresh oil, the only code I ever get is P2063 for cylinder #1 contribution/balance. ove replaced #1 injector with a tested and good injector. I've used a snap on Solis scanner and run a misfire test, somehow it passed while the truck was running rough, I've done an injector buzz test and all injectors pass. all ficm voltages are perfect, my icp is good, ipr valve isn't seized and seems to be operating just fine.
I'm at a loss everything I know how to test seems just fine. Could someone please give me some ideas on where to test next?
