lt1 runs way rich

Say guys I bought a 97 z with a procharger on it and the thing runs way way fat at idle. I dont know if its bad computer tune or fuel pressure regulators goofy. It has 30lbs injectors. The check engine light is on. I guess first thing would be to see where my fuel pressure is at and check the code its throwing. Anybody have any other suggestions.

Find those out first. It could be any number of things from bad oxygen sensors to misfiring ignition to leaky injectors.
