Anyone having any ideas on this one, I'd appreciate it. My Cummins M11 began "missing" ever so slightly on acceleration. That progressed till three days later, it's "missing" quite badly. Once I get it up to speed, it cruises fine but as I'm going up (or down) through the gears, it's like a gas engine when it's missing. So I deadhead 1200 miles home. My mechanic tests the fuel pump and it's good. He checked thoroughly for possible air leaks into the fuel system. Then he pulled the injectors and sent them out to be tested. Two had broken springs and one was over-fueling. So I'm back on the road with three new injectors. At first, there was a barely perceptible "stutter", but after about 300 miles, it's missing as bad as it was before the injectors were replaced. WTF? I don't know what to do now except drive it. If anyone recognizes this issue, I'd sure like to hear you have to say on it! Thanks
