OK my engine just started acting real crazy, it would idlefor a while then just die, I have ran a ton of test. Most of the time I get 412 - Cannot control rpm during KOER high RPM check (IACis a year old) the dizzy is new due to a PIP failure, also replaced the ICM aswell. One of the times I was running the KOER test and it would only read 6cylinders firing, any ideas what could cause this? This only happens every once in a while, I’m lost now.
