I have a Mk3 golf gti 8v engine code AGG which has done 133k miles and is in need of serious attention.
It has had a very rough idle for a while now, plus has had the stalling issues that appear in a lot of other threads. To solve this I have replaced all the relays, new plugs, leads and cleaned the original throttle body and then finally replaced it completely
However the car still stalls a lot when coming to stop and now it has started to become jumpy if you put your foot down further than half way
By this I mean you can actually see the revs jumping up a few hundred at a time and the car is kangarooing down the road (not a good look!!)
The cam belt is probably over due for replacement but would this be the cause of all these kind of symptoms?
Any suggestions would be appreciated
