hey guys I recently got my 420a turbo running. The car was previously ran N/A so it only has a few miles on the turbo. I have only hit roughly 4psi because I am still working on the tune (megasquirt ms3x standalone)
Yesterday morning the car gave me more trouble than usual starting. I didn't think much of it since I still need to play with the IAC settings since the turbo install. Yesterday afternoon leaving work it was a bear until it warmed up and the. Sounded like it was missing on one cylinder. So I pulled the spark plugs and the #4 spark plug's insulator nose was fractured.
I am still running the stock temp range plugs but plan to pick up a set 1 step colder. Could it be the plug got too hot? Or could it be from predetonation?
