no acceleration power on 1993 Honda Civic

My son replaced his distributor on his honda civic 1993 dx and now has no acceleration power. Any ideas? First problem was the car would die while he was driving and not start for a little bit. He has replaced several things and now this. Still don't know if the dying problem fixed because it won't go more than 5mph.

Does he still have the old distributer? Was the replacement dist. Re-man./new , or used?
