the truck only runs when you depress throttle (any amount) then runs and acellerates ok (smoth no shakes) until you return to idle..than immediatly stalls. seems like a major vacum leak, but I cant find one..alll hoses are good and mo cracks. Fuel pump was replaced 6,000 miles ago along with cao, rotor and whires..could it be the idle air control motor..how do I test it. does doge read through the computer. I taped on what i believe is the iac mtr. and it started..is it at the rear of injector towards the fire wall (i'm a chevy guy) thanks Jeff
