Question about 1993 Ford F250
Take it to Autozone or O'reilly and ask them to scan it with a tester. This should pinpoint the cylinder.
You could also try unplugging the injector wire one by one to isolate the cylinder if we are talking about a gas engine. The rpm should not drop if the cylinder is dead before you unplug it.
