Hey guys,

DTC is throwing out 0012 - Volume Air Flow Circuit Malfunction. Does this code deal with the mass air sensor? I do have the S-AFC currently plugged in also, I've zero'd the settings in the s-afc. I did some research about this code and it's possible that my mas harness or afc harness may not be plugged in or not correctly wired. My harness for the MAS is a 1g to 2g converstion harness for my 95-96 Summit MAS (I will go with a 501 mas quite soon). The harness is plugged in very good. I have to keep on the gas for the car to idle and even if I let it idle with me on the gas, it doesn't idle well at all. I didn't have the code pop up before DSMLink. BUT, the CEL would go on every time I'd be cruising on the highway and it'd would only go off if I let go of the throttle for a bit and get back on the throttle. I would love to say that it isn't a boost leak that's making me idle like this but I haven't done a boost leak test. I'd like to fix this issue before I go to Shane for a tune.

Thanks!
