Question about 2003 GMC Envoy
You will either need to reeducate the computer or have the dealer do it for you.
If you call them they can explain the procedure.
I believe it is start the car cold, let it run till warm.
Put your foot on the brake, put it in "D" then "R" then back to park, after that it could take as long as a month for the car to finnish learning.
But I would call the local Chevy dealer to get the low down for your vehical.
