Question turbo 3 idle, vsv advice

hi, in need of help with my mk3 turbo the other day I noticed two switch type objects connected to hosing and an electrical connector they both look the same both have a black cylinder on the end, these are just under the intake manifold the problem is I found one of them just hanging by the what looks like thin vacuum hosing Im thinking these are the vsv valves I was just wondering if these could cause a bad idle as the car sometimes idles at 500 rpm then sticks at 12oo rpm when hot,I have the code 51 but was just wondering if these could cause similar problems especially with one hanging off the engine for ages.is it me or do the supras seem to suffer idle problems all the time? it seems as common as head gasket problems ,which Ive had done Id be greatfull of any advice thanks.

Cool

search my posts and you'll find vsv info

vsv switch egr underside of the intake near the back there is one for fuel also worth looking at simple test determines if it's shot with an ohm meter to check continuity .
i replaced a lot of stuff getting to this one part that was toast
as soon as i replaced the egr vsv my mixture was good .
i thought oxygen sensor , cold start injector , cold start switch but the vsv did it
