2005 Chevrolet Trailblazer Repair Question
Chevrolet Trailblazer Rpm Problem
clean the throttle plate on both sides with choke cleaner. also was fan messed up? there is a thing that will set a code for fan being out of whack and cause idle/driveability problems. drive it for a while and see if it clears up, it may not but if the fan is messed up it may set a code.
