Does anyone know how to test the PCM to ensure everything is working properly? I connected a scan tool and there are no errors but I still have problems with Idle (sucking sound and occassional stall).

Thanks,

Check you IAC. If somethings wrong with your PCM, it will most likely present itself on one of the sensors.
