Just left CMP and had the strangest thing happen. First session, car is runningi fantastic then out of the blue it goes into an idle only mode. Let it cool down, starts up and runs fine. Go top up with gas and go out for second session, again car runs great and after a few laps goes into an idle only mode but this time it’s a very rough missing idle. Using the gas pedal does nothing. Loaded up and went home. Haven’t scanned for any codes yet, but wondering if anybody has ever experienced something like this?
