My air conditioner compressor froze up and broke the belt. The engine got up around 230°F momentarily. Now after it sets overnight, it won't start unless I give it a shot of starter fluid. After that it will start all day and be fine.

Losing prime? ECT reading wrong?

Hold accelerator down a little bit the next time you start it. If it starts right up, look into the IAC not opening up or the pintle is caked with carbon.

And don't use starting fluid, you could be buying an engine next.
