• 87... is it carbureted or fuel injected? If it is carbureted it could the idle screw has been messed with, or maybe the choke is stuck on. going 45 without touching th pedal would lead me to believe it is not the choke being stuck on, bt more the idle screw tampered(really tampered with) with or a stuck throttle cable or something. could be a number of issues.
  • ref. 1987 s-10 high idle speed the fuel is injected throght what looks like a carburater. there dosn't seem to be any idle screw ajustment trappere406
