Default 1986 Ford F150 302 multi point fuel injection

I purchased this truck about a year ago. When I purchased it it had a hesitation, stumbling issue on medium to hard acceleration. It has gotten worse. It seems to be tied to the outside air temperature. It does it all the time even when the outside temperatures are low, say 50 degrees, but gets progressively worse as the outside temperature goes up, say in the eighties.

Living in the Houston metro area, the temperature can start out in the morning in the high 40's and top out in the high 80's by mid afternoon in the spring time. This has given me an opportunity to see the operation at different outside temperatures.

Just wondering if anyone may have an idea which sensor could be causing the issue. I am not into the electronic engine set-up. I prefer the older less complicated models, but the truck was in such great shape and all original I couldn't pass it up. Unfortunately my knowledge of the 1986 and up vehicles is limited when it comes to the electronics.

Any assistance sure would be appreciated.
