rover 400 shaking

it needs a mechanic to look at it, I would start with the HT system

spark plus, spark leads or coil. I'd check the leads first.

By "shaking I am taking it you mean it is running a bit rough. A bit "three cylindery"? Is it worse when it is raining or the weather is damp? I had a

I have just had in a 214 with a similar fault, starts ok but after a few miles runs rough and may even stop, it turned out to be the king lead from the coil pack, when hot it arced over to a nearby bit of metal, a quick re-route and clean up and it is running fine again. 2 'mechanics' had spent hundreds of pounds and many hours trying to find that fault. Although quite why ht lead breaks down when hot I don't know.

In addition to what's been said try changing the distributor rotor arm, these have a tendency to crack and the coil then dumps its energy straight into the end of the camshaft instead of the HT leads like it should.

many thanks to everyone for the information my dad says its more of a jerking than a shaking it played up again today it happens when I put my foot down I'm sort on money atm cus of the previous work done will this be dear to sort out ? many thanks

I also had the distributor cap done too just before the head gasket went

replace the rotor arm, then move onto plugs and ht leads

I got four new spark plugs and new ht leads job done no more shaking or jerking now feels quicker too thanks for the input ppl many thanks :-)
