Can anyone help me with a datamaster scan?
Trying to pass emissions and not finding much help locally.
I have a 93 with an LT4 hotcam, headers, MSD and a tune. I left the stock O2's in and scanned the car. It showed a DTC error 13, failed Left O2. Left O2 MV was slow. Also, the car was in closed loop at idle but above 2500 rpms, it would go into open loop. So I figured I'd install heated O2's. Since then, the DTC error cleared but still the same problem...Not to mention, the left O2 MV is still slow.
I can't figure out what to do next.
