Surging and poor performance.....fuel filter? fuel pump?
Hey all, had an interesting day today. Boss needed my work truck so I drove my rig to Cincinnati and back for work today. Haven't had any problems out of it like this but on the way up, going up the hills it started surging like it was losing fuel or fire, pretty violently.
Started home and it did fine, then it started surging every now and then then progressively got worse. I realized at this point it was when I went past a certain point in the skinny pedal travel is when this got worse. Was thinking maybe gas, was down to half a tank, pulled over, filled up and dumped a bottle of fuel injector cleaner in. Ran fine for another 15-20 miles then started surging again, in almost a rythm, and I lost so much power that I couldn't even maintain 50 on I75, so I limped on the shoulder to the next exit, pulled over, cut the engine, topped off, engine was off about 4 minutes, started back up, everything was fine for about another 20 miles then it started again, but just slightly. By this point I was home so I haven't tried anything again.
Either way, it was directly related to the amount of travel on the pedal, and either topping off or shutting the engine off and turning it back on fixed it for a while.
The only other thing that I can think of being an influence is that it was absolutly pouring the rain most the whole time.
So, fuel filter? Fuel pump? Something else?
