    I have finally replaced the last four fuel injectors, and still have a vibration under load, and a rough idle. I have a 2007 C-15 acert 625hp with single turbo. Anyone have any thoughts?

    Search block on top right. Enter C 15 vibration. I recently saw one similar to that. It had a wire with insulation worn through and shorting. It was at rear of engine but for the camshaft sensor.

    are you 100% sure its a engine mechanical issue ? Im thinking more along the lines of electrical. Have you cleaned up the primary ECM power feed inside the left frame rail beside your left steer tire ? Have you checked all 3 power feeds to the ECM ? One will be from your fuse box, a second from that frame mounted 120 amp power junction / supply, and the 3rd directly from your batteries (in battery box )
