Flooding issue.
Hey everyone, just had a question to see if anyone could give me some insight. I have searched but not come up with anything really. I have a 92 Lt1 Car. The car is dumping fuel like crazy. It will startup, but wont hold an idle unless you put your foot on the gas and even then it doesnt sound great. After a while it wont start at all cause it fouls out the plugs. I have replaced the injectors, pcm, plugs obviously and still having this issue. No codes come up on my scanner. Any ideas?

the injectors are brand new. I can only test them at 1000rpm and they are all really bring and seem to be flashing but its tough to tell at that engine speed. No signs of fuel in the regulator vacuum hose. Car has 42psi KOEO and with it running it has about 38-40. Without keeping it running by playing with the throttle it dies out. Sounds ok for the first 2 seconds its on then it dies. It smokes like a bitch and smells like gas bigtime when we keep it running at around 1000 rpm. With the MAP unplugged it will stay on unassisted but runs at 1500rpm and doesn't sound great.

The dealership had said that the ECM was at fault. I sent the ECM out to be repaired and got it back with the same issue. I don't know if i should think the dealer was at fault in their diag, or if the repair was unsuccessful. I don't have any codes and i can view engine data. the ECU was a re-manufacturer in the first place.

Ok i swapped out the IAC. The car now actually was able to hold an idle, but it was running like ****. Smoking bad cause it was running rich as hell. After about 5 mins it died out and wont restart because the plugs are fouled. Maybe the IAC was bad and that's what killed the PCM in the first place?

Yea i know i need to do the adjustment procedure, thats why the idle is hunting from like 500-1500rpm. But that doesnt explain why the car is dumping fuel like crazy still and making it smoke/foul the plugs out.
