OK I have a 87, inline 6, 5 on the floor. I searched and couldn't find a answer and hope that someone can help me out as this has me stumped. When I go to engage my clutch (push the pedal to the floor) the Comanche dies. It will just spudder and die out. I cleaned my idle air control valve out with some throttle body cleaner and I put new plugs in. The wires looked good but I can change them if need be. Any thing else that I can try or do to figure out the problem? I do not think I have a vacuum leak but I could have looked passed something very easily and not known it.
