Exclamation Ingnition Coil Test

01 425 Expedition. Carburetor rebuilt 3 months ago, starts fine, idles fine. Give it throttle and she fires all over the place. How can I test ignition coil?

What do you mean by "fires all over the place"? That really don't make any sense.

Before you try to test the coil, try a new spark plug. Did you know spark plug caps fail more often than coils?

resistor caps are typically about 5000 ohms.. anything over that or open is junk.
