1985 GMC Sierra Repair Question
GMC Sierra Choke Problem
first check to see if choke works when cold, like closes then start up truck and see if it patiallyopens. then after warm see if choke blade is all the way open. if not then check for a vacuumleak or no hot air coming from exaust manifold. Then check to see about a carb rebuild, due to the alcohol in todays fuel it is probably needing one. At that timethere wasnt' much alcohol in fuel so accelerator pump may be bad.
