Truck jumping when given gas between 40 and 50 mph?
I have a 2002 Ford F150 Extended cab pu with 200,000 miles on it, and it started hesitating whenever i gave it a little extra gas whenever i was between 40 and 50 mph? anybody know might be the problem. I though it might be the fuel so i ran 93 octange in it for about 150 miles and put a fuel injector cleaner in the gas tank, but it still does it. Any advise would be appreciated?
