Engine Performance problem
2000 Chevy Suburban V8 Four Wheel Drive Automatic 98000. Miles
I had a code reader ran on the vehicle, it said the mass air flow senor & and the idle air control valve were bad, I have replaced both, but in cold weather it wont idle smooth, it just hunts back and fourth, but if I unplugg the mass airflow sensor it will run fine, I looked at the wires for the mafs, they appear to be ok, do you think the mafs could be bad, it was a reman. Thanks for your time.
