after starting it idles fine, but once in gear it misses on take off. Runs fine but if you stop for a light it acts like it wants to die. and while stopped it vibrates bad in tne steering wheel. Service engine light does not come on so dealer cannot figure it out. I am at a loss.
My 03 Trailblazer runs fine while moving, but once you stop at a light it idles rough and at times wants to die. While stopped it vibrates in the steering wheel. At loss, the engine lights don't come on so can't run a code. Any ideas?
