Yet another update.... went to park the truck just now after it sat for an hour and I started it with no issue, threw it in reverse and after a second it just died, motor shut no boggibg just shut. Truck started right back up fine and drove without issue besides sluggish and the mis. Backing into my driveway I tapped the gas for a second and it revved up then bogged like it was about to die then kicked back to normal.

Today I noticed around the base of my cts a tiny ring of coolabt slipping past the threads, so to try to make sure that wasnt causing issues I cleaned the threads then tightened slightly. I replaced the coil with a brand new coil and still misfire, I decided to retest fuel pressure and it was still good even at load, and I also wrapped my exhaust leak to make sure it is not causing false knock. Now this is important. I am still getting some knock counts but not always.... I noticed when the truck is really sluggish there is none, but when the truck is quicker it gathers knock counts quickly then goes back to being sluggish, this is even after a computer reset I will drive and it will already be sluggish. Does anyone have any idea what could be causing the truck to seemingly be retarding timing before I even drive???? Any ideas? and why it would snap out of it then get knock counts and re retard timing.
