Please Help ASAP
 
i just changed my plugs and wires and my car runs rough and backfires when you step on the gas and shakes horribly when you try to drive it then stalls with a fireball shooting from the carb. Did I mess up something? I have a 85 Chrysler 5th avenue 318

Numba ONE first "A-1" top banana question is, "how did it run" BEFORE you changed all this?

If the answer is, "better than it is now," then you either damaged a plug wire by yanking on them hard enough to damage the interior resistance material, or MORE likely, you have them in the incorrect position or firing order on the cap.

I bet you crossed a wire. I did the same thing.

Double check it.
