Default Air Diverter Valve buzzing?

my diverter valve or the relay for it has gone bad (electrical connector and funky device underneith maf sensor. it's making this crazy buzzing/whineing/humming noise please correct me if i'm refering to the wrong part. i checked the chiltons and it was little help. should i be worried about this part??? or just let it die and remove the whole air system?

seems like it's a dealer only part i've found some on ebay but i'm not sure if there what i'm looking for.... (part number wise)

went out and took a pic



arrow points to what i believe is one of the diverter valves for the air pump? correct me if i'm wrong...

You are correct, air diverter valves. The noise will go away once the garbage man picks up all that crap.

so pretty much just cap off the cat, vacc lines and a couple others, what about the pump? i'd need one of those air pump eliminator brackets or can i just leave it in there.........

how bad is the uninstallation? general time frame it should take me? just wondering if i should start this now or wait till my next couple days off. if it's a hour job w/ little problems i'm game right now, and as long as the pump can stay in.

any links to good elimintator/write-up is greatly appreciated.

You could leave the pump, but why, it's so damn ugly
Heres a link to some info on one i put together for my 86. The calculations were based on my 86, but the 85 should be identical.

the only reason i'd leave it was due to not having the elimenator. i need to buy one.
