I have recently swapped an L36 into a Fiero and I think I am having some issue with the idle. It seems to fluctuate more than I expect it to. Is this normal for the 3800? It's my first one.
It's a 100% stock tune (99 Grand Prix). The car still has it's pre-cat O2 sensor, the EGR has been removed (not disabled via HPT yet).
Other than that, the motor is stock. Attached is a log of it idling as well as the tune. Any help is appreciated.
