1997 Ford F-150 truck mileage: 79,000. The problem I'm having is with the fuel system. This is a problem that started all of a sudden. The truck runs fine first thing in the morning but when it heats up it, starts to run suggest like it's not getting enough gas. At a high speed (60 mph) it has a bad vibration. We changed out the spark plugs and fuel filter, which was pretty well clogged up. It ran fine for a while but seems to be a reoccurring problem. I feel that I may have got some bad gas when my problems first started. Any advise?
