mysterious 5kcstq problem

[<isham-research.freeserve.co.uk@pop.pol.net.uk>]

> Car starts fine, idles fine, and runs out fine until you come into boost.
> On boost the car begins to buck and breakup.  The behaviour is temperature
> sensitive, in that, if ambient is below 40 deg F, no breakup until say 1.2
> bar.  If ambient is above say 65 deg, occurs around 1.0 bar, and as car
> heats up to full operating temperature the threshold drops to as low as 0.7
> bar.

The relatively thick braided hose from the back of the inlet manifold
to the main wastegate attachment has become porous with age.  Feel
underneath it, especially at the wastegate end.
