i have a 1991 f-150 302 efi its got 95,000 on it i just replaced my plugs an wires none of my wires are sparking off eachother i checked at night to see if i could see something but it is misfiring when it idels i cant tell if it does when im driving but im positive it is. Im not sure if it my distrubter or not. an if your looking at your throttle bottle on the left side of it there will be a bracket mounted to it holding to different sensor wiring harness's one is plugged in to some sort of canaster mounted to throttle body its self an the other is just hanging above my alternater. i've looked all over the place try to find a sensor that plugs into but i cant. im thinking maybe thats what causing my miss fire. maybe so one can post a picture on here an i can see where it goes or describe it a little better
