I'm thinking the pickup coil in the distributor if 84 still is using a Duraspark. Should read 400-800 ohms across the colored leads. 84 is a little too new for me.

change the duraspark box on the fender, before it craps out in the middle of an intersection, and refuses to start ever again.

Actually, it could, my 84 had a computer, a feedback carb, and a digital dizzy like the 85's had.

Easiest way to determine what kind of ignition you have is to look at the dizzy; if it has an oval connector at the dizzy, you've got TFI. If you have a round-ish plug, you have Duraspark II.

First thing I'd check would be the codes. Look for a red connector on the pass side near the starter solenoid. If it has one, you have a computer. Have Autozone check the codes and let us know what you come up with.
