no power in high gear
I have an 87 4.9 with fuel injection.It seems to run ok in the lower gears but then it is in 4th gear it will run ok on flat groung but has no power on the hills.I have owned other 4.9s but this is the first one with fuel injection.It has a fresh complete tune up and the timing is set properly.Could it be one of the sensors ?
