After I puchased my 91 5.0 last sept. I bought an off road x pipe and exhaust for it. Before i had it put on i noticed the check engine light was staying on for the better part of the time. When I put the new exhaust on I also purchased two new o2 sensors and installed them as well. That has all been done about 5k miles ago. Now my check engine light is constantly going on and off. Is it possible that the sensors are already shot? What do I need to do?

+1. No sense wasting money guessing. especially when you cna pull the codes yourself for free using a paperclip or a wire.
