Whats wrong
Whats wrong My friend has 04 ZO6 and just got a g5x3 cam only installed by andy at A&A he has blackwing and lg long tubes he put 421 to the ground and car ran strong. Now when he punches it at around 3k rpm it has a little sputter and then around 4k it clears up and pulls like a mother. We just changed the plugs and they look good. we just took it out and the car threw a code p0116 we know it has something to do with coolant sensor but could that have anything to do with it? When just cruising around it runs great problem is only when he floors it and only happens around 3k and then clears up it almost feels like it is getting rich and then clears up and goes. bty when car was dynoed and tuned a/f was 13:1 across the board problem just started yesterday only thing that is different is weather is hotter.
