My car is a2003 Cadillac Seville sls with the 32v northstar engine. My car will start no problem but it won't stay running unless I keep pressing the gas. What would some common problems be? I just got my fuel evaporation canister purge solenoid replaced a few days ago I'm not sure if that could be contributin to the problem.

Fuel pressure regulator, throttle position sensor, not sure if the north star has cam sensors or not. Any check engine lights on?
