It's happened three times now, the first I put down to a hiccup in the system, but it's done it a further two times under the same circumstances so I thought I'd ask here for any pointers.
When travelling down the road at a steady pace off boost, if I drop a gear and give it full throttle, I get no boost at all......nothing. If I then take my foot off the accelerator and re-apply, it boosts fully as it should.
I've checked all the hoses, they are fine (they've all been replaced). I've just cleaned up the VSV's with some carb cleaner, but not re-tested yet, is there anything else I should look at.
Having searched a bit, I've come across this pressure tank thingy, I understand it's under the inlet manifold towards the rear of the engine? Could this be something I should look at?
