Health check at mrc 309bhp vac issues and decoke

Arthur

car runs well and pulls hard (although I haven't driven another B7 RS4)

what should i be looking for if you think it has other things wrong with it?

Graze

Vacuum system the obvious place to start.

I do think that a fair bit of the problems are resolved during cleaning when the silly 10p one way vacuum valve is changed.

Which valve is that?

The one that's located under the intake manifold and can only be got to by taking the whole thing off.
