Any Ideas?

I have an 89 2x4 4 cylinder carbureted manual and has driven fine until i took it in to get mu muffler repaired and a shop, since then it stalls after slowing to a stop and super poor gas mileage, also shakes at idle.

yesterday now i traveled to a town south of me, got there fine but had to fill up and figured i only got 8mpg, then i tried to get back on the highway and the truck shook and stuttered so bad that i couldnt get it past 45mph even if i had it floored and then once i limped it to a safe place it wouldnt start for over an hour and continued the same problems. i have no clue where to start looking for problems. any advice would be appreciated

Did the hose to the MAP sensor get messed up?
