My ZD30TD has developed a judder under acceleration around 2500 revs, but not all the time. Also power seems to be down a bit.
Any ideas what to look at? Motor is all stock and has around 225000k on it.
just got back from a long three day drive running perfectly,around the corner from home engine started running rough,sorta like running on three.
Engine starts fine but judders when revved.
Anyone got any ideas?
