Ford pinto Wrong firing order, won't idle?!

Ford pinto 2LT engine
firing order CW 1-3-4-2

i plugged wires wrong order by mistake.
i saw smoke out of carb through foam air filter and boom sound from exhaust, it was terrible.

so i corrected order, car hardly started after a few try, but it doesnt idle!
i opened idle screw from carb all the way.
Now it idles with vibration and loss of power

i removed every plug while car is working. Number 4 wire doesnt affect idle.
so my wire dead when exhaust "boom"?

what can be other problems?

thanks.
