hey new to this site but i have a 90 d150 with a 318 TBI. the truck has been dying on me every other day --i'll just be driving and it will sputter and die. it also idles very rough. i put the scanner on it and it gave me several codes. one being the map sensor. i changed the map sensor then it said tps.changed that . now it says pick up coil. i also changed that and it still runs the same. alot of people are telling me it sounds like the computer is going bad. what do you all think. any suggestions would be greatly appreciated because i dont know what else to do.
