95 gc miss while de-accelerating

Jeep idles fine accelerates fine, only problem is when I get up to speed and start to back off the gas a little it stumbles. This is especially prevalent when the cruise control is engaged and going downhill. Just had heads resurfaced, valves reseated. Still getting a Code 14 trouble code for MAP sensor even after changing out sensor. I feel like it is a sensor but I don't want to spend time and money changing out sensor after sensor till I get the right one. Anybody else had a problem like this?

I changed out the Throttle Position Sensor also with no luck. Checked for a leaking intake gasket by spraying starting fluid around intake while jeep is running. It never idled up or anything so I feel like the intake is fine. The service manager at the Jeep dealership said it could be a pressure transducer in the transmission (I trust that guy about as far as I can throw him). It stumbled once while idling yesterday and I got a O2 sensor code. Guess I'll try that next. Need to hear from you experts on this one, its driving me crazy. Thanks in advance.

Changed out the O2 sensor today-that's not it either.

Problem solved. Turns out the intake gasket was leaking after all. The distributor cap and rotor button wers shot as well. A big thanks to Dale for taking the time to give free advice. Much appreciated.
