My cars been randomly kangarooing and misfiring always after about 20 mins of driving.
It got so bad today it was flying all over the place. Couldnt pick up any speed whatsoever.
It randomly stalls aswell, but always starts first time. (apart from today it really struggled).
So i forked out £240 for AA membership.
AA guy hooked it up to the diagnostic and it came up with a rev error or rev sensor, he goes the cars that old it might not even be telling us the truth.
He recommended going to a VW specialist (midland VW etc) and maybe there machine can be more accurate.
Its had new fuel filter, HT Leads, Spark Plugs, relatively knew dizzie, rotor arm and igniton coli (cars been off road for 15 months they were done within that same year prior to being offroad).
I've checked ECU relay after driving, very warm.
Very pissed off after wasting 240 quid.
I drove home fine afterwards (he did spray all the sensors and connections).
Seems to me that its some kind of heat issue triggering it.
