Thanks for your help everyone.Replaced the plugs and plug leads and the problem seems to be sorted. Thanks

Did have a problem with power getting to the feul pump as wires were perished,but got an electrician to redo all the wires to the feul pump.Feul filter was replaced.Is there something else in the feul line that I can check? PS: thanks for the advice

Yes,but don't think it is the plugs as it was serviced recently.Could it have something to do with the air?Sometimes when I stop it also idles irregular with the revs going up and down the whole time.

Hi evryone,I have a Discovery V8i 1998 and my problem is that when driving the car jerks.Does not happen all of the time,but more often than not.If I ease off the accellarator a bit it stops.Don't think it's the diff.Any help appreciated. Thanks

Had the same problem.Check if power is getting to your feul pump at the back.In my case some of the wires running from the front to the back were worn out.
