Default C4 start and stall.

I have having an issue with my 87 corvette, where when you start the car it immediately stalls out within 4 seconds does not idle. If I hit the throttle I can sometimes keep it alive. I was wondering if anyone has reconditions. I think I’m going to replace the main O2 on the driver side next.

Some recent things I’ve done.
replaced plenum gaskets
fuel injectors (off zip corvette stock injectors)
intake gaskets
EGR temp sensor.

some other things that were replaced on the car
fuel pump
fuel filter
MAF

While you say you've replaced the fuel pump and filter, have you checked fuel pressure to ensure it isn't fuel starvation.

Have you checked the Idle Air Control Solenoid ? a stuck/bad can cause that
