Engine Performance problem
1991 Ford F150 6 cyl Two Wheel Drive Manual 125000 miles
First incident. The engine starting hesitating and sputtering while driving at a constant 40mph until it died out. I was not able to start it afterwards but was successful the next day. Second incident, same conditions only this time I was able to start it with continuously pumping it gas. I assumed it was faulty injectors so applied cleaner into the gas. I did this approximately 3 times over the next 2 years and the truck never died during this time. Last week I was driving on the freeway and it started to sputter. I pulled over at a station, left the engine running and added Lucas injector cleaner/fuel additive and drove approx. 70miles without problems. Today, it sputtered/hesitated again until the engine died but I was able to instantly start it up and drive home without problem. This happened while still running with the same fuel and injector cleaner. The fuel filter is about 2 years old. The plugs/wires are about 2 1/2 months old. Also, the check engine light has never come on while driving except when the truck is acting up like described.
have the same problem?
