Hello, I’m dealing with a p0300 and
p0301-308, misfire on all 8. Car is a 2017 gt, 6r80, 2018 manifold locked out, free flowing exhaust, Paxton 3.6 pulley on 93 with boostane lund tuned. Filled up with 93 and boostane and drove the car for half a tank over two days, parked it for 2-3 days and changed the belt and it started misfiring after that. Car starts fine and idles fine but you can hear the misfires from the small exhaust pops but won’t throw a code. Idle rev and hold 1-2k and she’ll throw p0300-p0308 after a few seconds. Drives fine and pulls hard. She’s on a clean tank of 93 now, new spark plugs, new o2s, crank relearn, smoke test for vacuum leaks, compression tested, leak down test, and everything looks great. Any advice, tips or ideas of what it could be, or how I should go about figuring this out? Thanks!
