Car runs great. The only problem is after it warms up, I can't take my foot off the gas because it will stall. It starts right up every time, but I can't take my foot off the gas. No engine light, no smoke, no sputtering or loss of acceleration, just stalls.

Hi,

The most common cause of this is an engine vacuum leak. If you haven't checked for leaks, that is where I would suggest starting.

Take a look at this link. It explains how to find and repair vacuum leaks. Let me know if you are comfortable performing them.

Let me know.
