problem after changin rats nest

[yamaster]

i replace all the pipes in the rats nest with new silicon pipng.  now the car is hunting on idel.  im nearly sure that i put the vacum pipes that go onto the  bulk head side of the plenum are not in the right place.  can anybody tell me where they should go into. i tink there is around 4 pipes.   where shold the boost sencor go into?


any help would be great.:cheers

You sure? It looks like it goes down to solenoid D (EGR).

yea there is only one pipe on conected a the back of the plenum and the one that is connectted has a check valve thingy so it has to be the other one.

your car wont have EGR. If it does go down to EGR ( i cant see clearly enough in that pci...shud have gone to spec savers), then just cap off the nipple on the plenum and you ll be fine
EGR is for us spec cars to help them thru emmisions

a crap was hopping it was suposed to go somewhere.  the car is over boosting all the time,.  wonder what it could be.

Have you got a performance downpipe ? And you are using a boost controller ? If yes to the downpipe then that could cause overboost.
