bad fuel / rough idle / CEL
Working on a 2015 chevy 2500 6.0 136000 miles. ROUGH idle, 6 mph, backfiring, someone change cats from collectors to single pipe. Changed plugs, original plugs, they or someone changed o2 sensors. They put walker O2's. Cleaned the MAF. Running extremally rich.
thanks for any assistance.
