Question about 2003 GMC Envoy
I replaced my battery today on my 2003 GMC Envoy. Now it will not idle correctly. Is it because the computer needs to "relearn" whatever? If so, how long does that normally take?
Got a solution for you on this. There is a small sensor, called the MAP sensor.
It is located on the top of the engine. You will see a blue sticker with Delco Motors 5V GND written on it. Has a wiring harness that you can pry up and
pull off. Unplug the wiring harness and plug it back in. You may need to reset the code errors. I had mine at a mechanic, and he did that , reset the code errors and it solved the problem.
