Wont stay running
Did a search and have not found much i have not tried, my problem is confusing me.
Have a 305TBI on a 88 Firebird and the engine starts up, but sounds a little rough, after a couple seconds it starts to sputter and die off, light tapping on gas might let it last a little longer, but anything past a tap kills it outright. It appears to be flooding out.
Have replaced spark plugs/wires, oxygen sensor, MAP sensor, Throttle position sensor, and rebuilt the fuel pressure regulator. Not getting any codes so am slightly baffled.
