I have a 1994 Chevy Corsica with a 3.1 liter engine. The engine dies every so often when it hot and wont restart until 4-5 minutes later. Have checked vaccum lines, map sensor, and replaced temp sensor. I also completly flushed cooling system. It seems to have helped the car run a bit cooler but it still dies. What else can I check?

The idle flare up is when u start it the rpms go above normal idle speed for about 3-5 seconds then comes down to normal idle speed,if this car is stalling in park then all u need to do is remove the air cleaner from the throttle body and clean the the throttle blade and bore with a rag with some throttle plate cleaner on it that u can buy in a spray can at all auto parts stores and also take the idle control solenoid offhte side of the throttle body which is near the oil cap and has 2 t20torx head screws holding it on and clean the cone shaped plunger on the end of it with the same cleaner,after these two things are cleaned,reassemble the air cleaner and take it for a short ride so it can relearn idle,hope this helps
