Go to the "Do it Yourself" site on our home page. Scroll down till you find the directions needed. NOTE: Is there power to the coil?

Okay, I need you to check the wiring to the coils. There could be a break in one of them and you make contact once in a while. Move them around when starting the vehicle.

Let me know.

If you have power to the coil, the next check is the ignition module. It is in the distributor.

Sorry... I was thinking they still had them in 87. The only other thing is either the crank sensor, a broken wire, or the PCM.
