1996 Pontiac Grand Am 4 cyl Two Wheel Drive Manual 157000 miles
I have a 96 Grand Am SE throwing two codes when hooked to a hand held reader. The first is P0172, which is a fuel trim condition (the car is running rich judging from the sound of the engine and the exhaust). This code, according to the readout it says to suspect the Mass Air Flow Sensor if bank one and two O2 sensors code together. The second code, P0141, states that there's an issue with the Bank 1 Sensor 2. My question is this, should I suspect the Mass Air Flow sensor, or the oxygen sensor, or something else that the computer isn't picking up on that's causing it to run rich, and if so where and how does one go about fixing this.
have the same problem?
