I just finished the head gasket job on my Grand Am.
The problem is that it won't start without giving it gas, and I have to throttle the pedal to keep it running. Once the engine is warm, it runs great and starts right away.

I cleaned the IAC valve and port, checked for vacuum leaks, the coolant system has no air in it and the temp sensor appears to be working, the fuel pressure is at 55 psi...
