It's not going to be a crossed wire if your truck was running just fine before. It's also making me think it's not carburator related for the same reason. Something had to have failed in order for it to suddenly start running like crap. Maybe something to do with the advance on the distributor, maybe that timing module that Cableguy is talking about.
