my lt1 running so rich it dies
i have been chasing this problem for a long time. the car started running rich and the starts got harder and harder. it runs soo rich you have to keep it running and clear the fuel out. what could cause this?

i have checked fuel pressure, fuel pressure regulator, leaky injectors, throttle positioning sensor, coolant temp sensor, exhaust restriction, o2s, maf, vacuum, tried another computer from tha same year lt1. my mods are pp heads, cam sililiar to a hotcam, polished intake, lts, cai, and tune done by a shop near me. the car was tuned over a year ago so i didnt think that could have caused this problem but i swapped the computer just to see and its the same.
