F.A.O RICHANDHAZEL/TINMAN

I posted on here about my fuel prob' a few weeks ago,and got some welcome tips but it still haunts me .Basicly my mk2 gti jerks when coming on and off the accelorator.It is worse the lower the gear,ive been round the houses and replaced nearly every thing-but the problem remains.Where is the control unit? I thought it was the 1 under the flimsy plastic cover on the left hand side of the bulk head.I saw the post  suggesting that there is one behind the centre consol.
Is this the 1 that controls the idle speed valve?
I can try this as a last resort!!!

CHEERS.

The control box for the idle speed control valve is behind the centre console. What have you replaced so far?

Sorry mate, been away all weekend............VW-Action......put it in your diary for next year!
I'll have to have a read tomorrow to get back up to speed and find out where we are with this.

And more recently,the throttle body and switches.

How do you get to this 'control unit' please.AND what does it look like/and whats its main control over?

Hmmm, not sure if this will be of any help to you but here is a troubleshooting guide for the digifant fuel system:-

I've really been busy today had to rescue a mate who's Rover 420 SLi broke down on him and then fixed a problem on another mates 1.6 Golf. Haven't really had a chance to look into this for you, but hopefully can dig something out for you tomorrow.

Did you try testing the fuel mixture?

[richandhazel]

There are a series of electrical tests that you can do at the Difigant and ignition control unit connectors that will test the various components in your system.
Would you like me to dig out the procedure and table?

Yes please,are they easy to follow for a layman?
Thanks for your time..

Finally sorted it........spent most of the day re-vamping my website. So time consuming especially when you are a complete novice as I am.
Anyway, here is the info. I think it should be straight forward enough:-

Let me know if there is any problems with pictures or tables not coming up or the webpage not working correctly......I'm fairly certain its OK, but I've said that before.  

Good luck.
