swapping a/f sensors.
Hadn't driven the car in months and it was low on fuel.Kicked an 0171,0300,0301,0303.0305 and an 1135 code. 500 miles ago I had replaced the bank one sensor, but had some cam solenoid hiccups, seemingly cured by an oil change.
Pulled the bank one and two upstream sensors. Bank 2 nice and grey, bank one black, as the fuel was just dumping on it according to the data stream. carb cleaner time. Swapped sensors front to rear. Briefly got a 1135 code.
sensor 1-1 is still sticking at.66. no voltage change
Drove the car at 4k rpm for 20 minutes. voltage on 1-1 not moving. Briefly a 1135 but it cleared itself
so next we clean up the maf after dinner
