Q: Engine light and throttle body light come on every morning when first start

I installed a crate engine and drove for about 700 miles with no issues and then I had the a/c recharged from having replace the engine. The next day I started it in the morning to go to work and the check engine and throttle body lights came on, I have a handheld scanner and it said MAP sensor P0108. So I replace the map sensor and the next day same thing when I started it. Same code P0108 map sensor, so then I took it to a local shop and had them hook it to there computer and they got same thing. So I replaced the map sensor again and same thing happen the next morning, so I took it back and the scan it and said I need to replace the throttle body. So I did and reset it to what the manual said and the next morning yep same thing, so then I took it to the dealer to have them check it and they had know idea. So 170.00 dollars later I took it back home, I check all wiring and connector's could not find nothing wrong except the air charge temp sensor was broken so I replaced it.
