Help needed with a stalling C4
I have an 85 C4 anf i need some advice to fix a stalling problem on my car. It stalls when it starts unless you feather the throttle for approx 30 seconds then it runs good. Any tips would be greatly appreciated. Thanks

You might also check the fuel pump relay. If its failed the pump now has to get power thru the low oil pressure switch, that has to see several psi of oil pressure before it sends power to the fuel pump.
Best guess is some issue with the cold start circuit.
You might also see what fuel pressure is and if its bled off completely, and if its loosing pressure or slow to build. Having to help the idle for a second or 2 might mean the filter is clogged and fuel is having trouble getting to the injectors at good pressure. Pressure test the fuel pump and observe leak down time when off.
