My Blazer is reving up to about 2500 rpm's when I put it in park sometimes. It also will go about 40 miles an hour without me touching the throttle. It will lunge forward as soon as I take my foot off the brake. I changed the idol control valve per advice from a shop here in town. Obviously did not fix the problem. EGR maybe??? Im at a loss at this point. HELP???
