Shudder/Bucking 5.4L Engine
Got a 2000 E150 w/ 5.4L and 77k on the clock and engine seems to be bucking/shuddering, this started happening a few days ago and I kind of thought it might be the ujoints but when I kept van in park with brake on and reved engine it still happens. Tonight the check engine light just came on. Ive never changed the plugs on it. Curious to what this might be, any suggestions ?
Thanks,
