1989 vette

Car will start fine but runs very rough stalling unless you gas it to keep it running...as soon as it hits 195 degrees it clears up and runs well....any suggestions.

I had the same problem with mine. It was a dirty #4 injector. Check the tps sensor as well. Iac might be sticking too. Most of the problem was the injector.
