motorway problem!!! ---- FIXED!!!!!!!!

It sounds as if you are getting a lean cut. Run the engine up to temp, then get hold of the carb and gently rock it back and forth. (If these carbs are the same as the older Audi 80 carbs, it will have a rubber sandwhich plate at the bottom of it and these split.) If the revs go up and down with the rocking, then this rubber plate is split.
Check the float level as well.

the carb is abit loose on the manifold so i will have a look and tighten it, the rubber flange thing i onyl a year old, along with the carb, so i doubt they will be old or broken. How do i check float level?

One thing at a time. Tighten down the carb first, but you may well need a new gasket. That will probably cure the problem. Then try the car.
As for the float, look in the haynes for info about that. TBH, it should not need touching unless someone has buggered about with it before.

stay off the motorway 

haha yer i think thats the solution. although i had it again today on normal roads.

Right, had it again, pulled over, opened the bonnet, had a play with the carb, and noticed the sandwich plate bewteen carb and manifold has a crack, so my money is on that, so i'l order another one today and see if that sorts it out.

need quick reply-
where can i get a new gasket to replace the broken one? do fast road cars sell it? or GSF or ECP?

is that one for the weber? cos i had a look at mine and it has 4 screws holding it down.

[rubjonny]

is it the one under the webber or the one on the actual manifold?
