Hi I've a 2.1 87 dj and at around 2000 revs or just before,it starts to judder then stops as the revs climb past 2200 or there abouts,if I let it sit there it just keeps doing it.any ideas please

Hi there, I think it could be a spark plug issue either one has failed or the gap is too close together. It could be a faulty lead where the spark is tracking down the side of the plug or the timing could be slightly out. Hope this helps. It's worth ruling out the simple and less expensive things first.

Wasn't there someone on here not so long ago with a similar problem that was caused by the resonance effect of an oval tyre?

Yes I can remember reading about the tire one,and have changed plugs etc,but drove it around the weekend and after a few hours around the city it was getting very bad.
