If you back off the throttle and then go back on the car is very jerky. It will also occasionally be hesitant when accelerating. It has had new plugs, distributor cap and rotor arm; the leads are about 3 years old. It feels more like a fuelling/metering fault. Any ideas?

Not too sure about the 2.0L, but my Golf 2.8L of the same age had similar issues. Turned out to be corroded wires going into the multiplug which fits onto the MAF which was messing up the air/fuel mix. The backing off the throttle and then back on would rock the engine a bit which caused a bad connection where the wire was corroded.

Well - for the "It will also occasionally be hesitant when accelerating" - i've two mark 3 Golf's - both benefited hugely from new plugs, new arm & dizzy cap. I suspect after three years there is some degredation there. Typical symptom is having no power at idle/low revs - or a mild misfire.

I'd change those first, then see what happens for the other fault.

Cleaning the MAF won't hurt either.

Had a diagnostic - turned out to be the air mass sensor. Running fine now.
