I have a 95 Mack with a E7 350 that since I purchased has had to be primed every morning before it'll start. If I turn it off for an hour or two it doesn't give me much trouble. Before recently that was the only problem, it ran like a champ. Now it all of a sudden started surging rpms when i hammer down, empty, on an incline, or when loaded, causing the rpms to ramp, but no extra power. I can't even climb the ramp in the quarry without dropping to 2nd or 3rd gear, when id be able to take it in 5th given I had momentum. It shakes if I shift quickly, I have to ease off and let it "catch up". I'm changing the fuel filters tomorrow, but I was told the likely suspect is fuel injectors? Anyone else have a similar problem?
