Engine Performance problem
2005 GMC Envoy 6 cyl Two Wheel Drive Automatic 113125 miles
I received the error code P0128. I believe the problem is with the t-stat or with the idle air control valve. I found a t-stat to be replaced but cannot find a air control valve. Can you please help me identify where I can find one? Thanks.
