How to test A/F ratio
My 05 gt is throwing a p2270 code every once in a while, which is bank 1 sensor 2 stuck lean. If i look at my obd2 it shows the the bank 2 sensor 2 is also right there with it. Im wondering if i am runing lean or if it is due to the long tube headers and exhaust setup flowing air easier. I want to see if there Is there a way to test the A/F raito before i go rush to buy a tuner and get a tune to see if that fixes it.
