hesitation

Alright mate, i know this may sound stupid but you want to change your distributor and your spark leads. mine was doing exactly the same thing, and i changed them and it's sorted it.. well i changed distributor at first n thought i had sorted it, then it started again, so changed the leads to and it's been spot on since. also i had a funny smell from mine, but i had the plug to the maf unplugged, but when i got my new one in the smell stopped. i know what you mean by hot kind of smell..

You changed the hole distributer or just the rotor arm and cap?

cap and arm is all that are needed.

look in here - has the diagrams for the dizzy and belt:

Hmmm. my mk3 you can change the belt simpler than in your guide...except I don't have a guide that shows how to do it when you don't have air conditioning..maybe someone does??It would help as I will change the belt and water pump if my golf passes the MOT in a few weeks time.

I used to have the same thing on my old car.
After changing all the usual bits and checking that everything was clean and functioning + new battery, I still had it.
At around 3k revs it used to do the annoying lag thing
RJ gave me some info about calibrating the 8v (what's yours?) TB/fuel system with VAGcom and that sorted it out.

Sorry for being a bit vague but this was years ago, still something to consider if the problem persists.

oh mine laggy from 1k up to about 3k

yeah, just the cap and and rotary arm mate, i got them from wilco, 8 quid for the distributor and 3 for the rotary arm, it's worth a shot. if not I'd try some new leads. that's sorted mine completely. leads were 31 quid from halfords, their cheaper than wilco n i needed them quick. it's worth doing just to rule things out. my spark/ignition leads looked fine to me, but that was the problem. also have you cleaned your MAF? i got some electrical contact cleaner from Maplin. was like 3 quid. like i said it's worth doing, i never thought it'd solve the problem but was as easy as that. hope this helps mate. let me know how you get on.
