Ok...The car had CEL's for O2 sensors and the cat. Replaced all these items. Replace plug wires as well. The CEL comes back and here is the read out:
0171: Bank 1 Too Lean
0430:Catalyst system for Bank 2 below thresh hold
0103:Oxygen sensor for bank 1 too slow
0420:Catalyst system for Bank 1 below thresh hold
1131:Lack of HO2S switch indicated lean
0174:Bank 2 too lean
After explaing to the guy at autozone everything that had been replaced, I asked if the problem could simply be my precats. He had no idea what I was talking about, but suggested it was the MAF. Any takers? TIA...
