Question about 1997 Pontiac Grand Am
I 'm reading trouble code... P0 134, o2 sensor, No Activity, bank 1 sensor 1....are there two sensors, one at the exhaust manifold and one by the catalytic converter? I see what appears to be one at the exhaust manifold right before the exhaust pipe connection.
Also reading....P0 171, system to lean, bank 1...I'm hoping this will clear when the o2 sensor is replaced.
BANK 1 SENSOR 1 IS THE ONE IN THE EXHAUST MANIFOLD. BANK 2 SENSOR 2 IS BELOW THE CATALYTIC CONVERTER.
P0171 SHOULD GO AWAY WITH A GOOD O2 SENSOR BUT DO CHECK FOR VACUUM LEAKS TO BE SURE. 3.1/3.4L ENGINES HAVE A BAD DESIGN INTAKE MANIFOLD GASKET, THE LEAK OIL, COOLANT, AND AIR.
