Gaaaaah! If its not one thing, its something else. It's now started shuddering from left to right when I stop at idle, when hot. Anyone throw any light on this? I do have a diesel leak from the base of one of the injector pipes but at the pump end, bottom one nearest the block I think, looks a bitch to reach for tightening. I dont think this is the cause, more like an electronic engine mount but dont think a 96 motor will have them will it? If you switch off for a minute, then restart, the shudder is gone, and only appears at idle anyway, even 1k rpm its as smooth as butter, but at 800 idle its rough sometimes.
