Cripes, I don't understand why this cars arent kicking out CEL for these misfires they're pretty traumatic, most cars catch misfires and you won't even know they happened you won't hear or feel them nothing which can be super annoying but at the same time helpful.
So I actually found 100 point unleaded race fuel put 4 gallons with 91 full tank. My brain hurts too much to try to figure out what the octane rating would be
So it's definitely not fuel, I just had major major misfires and it's weird it's at a partial throttle coming uphill with load. I can almost get it to just continue to misfire at a certain position on the throttle. It's absolutely horrible. When I put the stock mid pipes back on I'll have my guy pulled the plugs and check each one to see if there's anything that has happened to the plugs. This is so disappointing and frustrating
