ok...i have a B16 CRX that i just installed a JRSC on. i'm running the PR-3 ecu along with the SMC for fueling. everything runs perfect except for the following. after driving around for about 30-60 minutes, the CEL comes on and the ECU flashes the "emissions" code. does anyone know what this could be? i guess i'm confused on what its using for a sensor to trip this code. does it have to do with the evap purge valve? again, the car runs fine but this CEL is starting to **** me off.

thanks for any insight
