Correct ballast resistor

The way I read my electrical diagram it would be the 5.4 ohm side that is not needed. I still need the 0.5 ohm side for the coil. I’ve been running a 1.4 ohm resistor instead of the 0.5. Could that cause problems?
Correct, what I was attempting to point out. The coil side is the lower resistance. Maybe a high speed miss with more resistance. Look up your coil specs. The coil/ resistor specs, over the years are in the back end of chapter 8 in the manuals. You can download them free, from MyMopar.com. Several of them got them because of some of the guys right here
