The coil wire runs from a little black plastic cover about as big as your fist located near the right (drivers) wheel well. The wire, (look at your plug wires coming out of the valve cover for size and color), runs to the distributor (that black cover at the front of the valve cover). Trace the wire and see if it's touching anything really hot.
yhis may or may not have any effect.
