My 92 Loyale is having a hard time staying running when i first start it. I have to wait 20 seconds in between tries and it just keeps sputtering and shutting off. its fuel injected and it quit going into the cold start high idle. after trying to start it for about 10 minutes i can start it by slowly tapping the gas and bringing the idle slowly higher. Too much gas and it boggs out. after its warm it drives fine

 

please help out if you have had a similar problem

Sounds like the Coolant temperature sensor. It has 2 wires, screws into the housing under where the thermostat is.
