Can anyone tell me something specific for why my engine light might come on after idling for a minute or so, even while driving? It goes off when I push the gas, then comes on after I let off of the gas. I have read the DME code (1222 - Air/Fuel Mix), which gives me several different things to try, such as Mass Air Flow Meter, Valve Adjustment, New plugs, wires, etc., and maybe the car has run out of gas (Which it hasn't).
