i need a new map sensor or just the whole set up

This issue started as intermittent, then now has developed to anytime the car is not under a heavy load it will not fire. Compression is 140-150 across all cylinders, i have changed plug, wires, and cap. Timing is set at 10*.

I have a factory radio in great shape. The tape player does not work but radio and eq work great. Make me an offer.

What program do you use?
