Why is my truck Losing power?
Have a 92 Ford F-250 triton v10
straight 6 with a 5 speed. Truck loses
speed uphill and when pulling a trailer
its even worst, any suggestions on
what to check or replace first? Has
125,xxx miles on it. Blew a little white
smoke the other day hauling a trailer
uphill but never got hot and when
back to flat ground did great
