I have a 2008 Chevy colorado that is a 2.9 5spd - Starting up a steep grade from a stop makes it worse. It does not feel like a miss and the rpms never rise when it does this. I cleaned the electric throttle control and checked for codes and none are present. Any ideas what this could be?
have the same problem?
