I have had my PFC for about 6 months. I had it installed 6 months ago and then put my car into storage. The check engine light was fine when I orignally had it installed. After disconnecting and reconnecting the PFC my check engine is now illuminated. I tried disconnecting and reconnecting the batery cables and I let the car idle for 30mins after reconnecting the PFC as intstructed for first installation. Does anyone know how I can get the check engine light off? Is it possible that it could be something else not PFC related?? thanks.
