So any way did some digging and scanned my odb 1 codes and got a 41 and a 79
79 a/c on durring test, it was not on, is this a common code?
41 i'm guessing is maybe an O2 sensor?
which one ? how any are there?


Also tried running the engine running test but had trouble with the codes
any help?

Any help would be apriciated,
Thanks
