940 turbo vacuum pipes

reijo5 · May 17th, 2018, 18:24

Had my engine out and stripped for a few months , and I can’t remember where
All the vacuum pipes go

1 T,s off to 2 , 1 goes to a valve that has a feed from the exhaust manifold ,
And 2 come from the (is it .)? Idle stabilisation valve , obviously 1goes to the inlet manifold , any help would be appreciated

Cheers

Jamie

What year?

Early models have EGR, but no vac pipes I can remember.
Idle valve has big pipes that bypass the throttle body.

Its unlikley vac pipes can cause stalling, the air flow is too small, but there are some large bore and small bore ones (nipple is also a restrictor with just a small hole)

Will it not idle when warm or does it perhaps just stall after acceleration? If its the latter your dump valve isn't working.

That is a very good point. Pull the cbv valve (3 bolts on the turbo cold side) and check the diaphram.
