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.
