Angry Running Rough/Misfire

I posted this in the regular forum with no response so hopefully I'll get some under this section.

CEL light is back on and spitting and sputtering again! Replaced distrib and rotor last time(August '09) and it took care of the problem(not injectors). Does anyone know if something could be killing the distributor cap and rotor? Replaced with AC Delco parts so shouldn't be bad yet. Plugs are AC Delco and replaced last time when this happened so wouldn't think it would be those either. How do you tell if a plug is fouled? FYI: seems to be worse when running steady.

It also sounds like I have an exhaust leak under the hood. Could this have something to do with it?

Thanks,
