5.0gxi-d. this boat got a new long block motor installed. Mechanic gave it back to me with a hesitant idle and hard start. Had to open throttle to keep it running.
It starts immediately every time but stalls after a second or two. I replaced iac,dissy,rotor,pressure regulator,fuel pump, and tps. After playing around with it today I have narrowed it down to the tps sensor. If tps is unplugged it runs at idle perfect on start up. If I plug it in it stalls or catches itself at stall and hesitation idle. Does the tps need to be programmed on a scan tool ? Like the mechanic just did t want to adjust it properly ? Thanks
