Why does it seem like my injectors are stuck open?

Out of the blue my injectors started dumping loads of fuel out of them. I ran a diagnostic and it showed a faulty MAP sensor. Replaced it. Then it showed a faulty TPS. I tested the TPS and rechecked the codes and it cleared. However, it is still flooding the engine with gas. Thius is a TBI 350, totally stock. I'm stumped. What else should I check or change?
