Engine Performance problem
1997 Pontiac Firebird 6 cyl Two Wheel Drive Automatic 139000 miles
Auto Zone used the OBD II and said the fuel system for bank 1 was too rich, then they tell you it's either a MAF or Oxygen Sensor, how can I determine which it is so I don't have to buy both. They also said there was a misfire in cylinder 3, then they tell you it either sparkplugs, wires, coil, vacuum leak ect, how do I determine more accurately what the real problem is so I'm not buying all kinds of unneccessary parts.
have the same problem?
