Trouble code P1537
Check engine light is on and is throwing this code. The code reader says: "Manf Cntrl Veh Speed-Idle Speed Control-Auxiliary Inputs". Logged on here and did a search. Found a post that said it means: "Intake Manifold Runner Control valve stuck open". Can't find either of these things in my Haynes manual, and the boys at the auto parts store can't help me. Is this the Idle Air Control valve? What am I looking for here? Help!
