Code 66

cali 5.0 · September 24th, 2006, 12:07 AM

when i turn my car on it tends to idle real bad when cold but if i unplug the mass air flow sensor the idle picks up and does fine, and i have a code 66 4 the mass air flow sensor. ichecked the voltage and its the same as the source... i ohmed out the mass air flow sensor and it has continuity but when i plug the damn connector back in the idle drops right back down to the point where it wants to cut off...
