Question about 1997 Pontiac Grand Am
The trouble codes listed are defined as:
P0141 Oxygen Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
P0300 Random/Multiple Cylinder Misfire Detected
P0331 Knock Sensor 2 Circuit Range/Performance (Bank 2)
PO300 & PO331 are possibly symptomatic of issues caused by PO141, which would have a direct influence on the air/fuel mxture... which could cause missing and knocking.
So the first thing I would try is replacing the Bank 2 Oxygen Sensor, after making sure the wiring and connections to that sensor are in good shape.
Does the engine show any physical issues such as loosing coolant, smoking exhaust, overheating? A blown or leaking head gasket on the #2 bank could also present these (among other)
Good luck and let me know how it goes!
