Heres the deal. I have a 1996 Chevy Silverado 1500 V8 5.7 liter. I took
my truck to AutoZone for their free computer dianostic check because my
check engine light was on. Their computer said I needed to change Bank
1 and Band 2... Sensor 1 on both banks. So I did. While I was at it I
also changed all the plugs and the plug wires.
Anyway... after about 45 minutes of highway driving my check engine
light come on and the engine appeared not to have that much horsepower.
Took it back to Autozone, put it on their computer (a different
AutoZone by the way) and again it downloaded a 131 and 151 again for
the same sensors.
Heres the error messages:
P0131 "Heated Oxygen Sensor" (HOS2) Circuit Low Voltage Bank 1, Sensor
P0151 "Heated Oxygen Sensor" (HOS2) Circuit Low Voltage Bank 2, Sensor
Any idea what might be causing the same failure even after replacing
