i have 2001 ST JOB 1 77k. The check engine light came on a few days ago. It remained on for two days then today it was gone. I noticed that it would lose a little power if i goosed the peddle(like it was not getting gas or air). I took it to a local auto parts store to read the codes: Pending Codes-P1132 Lack Of HO2S1 Switches-Rich (Bank 1 Sensor 1)
Freeze Codes-P1131 Lack Of HO2S1 Switches-Lean (Bank 1 Sensor 1)
The trouble light is still gone but if i leave it in park and rev up the engine until it reached 4rpms the engine shudders(like it was not getting gas or air).
The auto parts person suggested to buy oxygen sensor part for $79. My question is am i on the right track, or could it be the fuel filter or maybe the pump? Also just wanted to say this is the best site ever. Any help would be greatly appreciated.
