PO307 andPO300 Codes, Misfire Help I had an LS6 intake and ASP crank pulley installed last week. Only drove the car about 200 miles before heading to the track on the weekend. After my 3rd pass the check engine light came on. My friend scanned it and it shows.
PO300 and PO307 The is a definite miss to the car. I know I hit the rev limited acouple times
however, there is no mechanical sound to indicate a bent valve or pushrod.
I also pulled the plug on #7 and it looks fine. Any advice would be greatly appreciated.
