[neo32]

yeah its like buzzing what does this mean

i didint take it off the manifold just unbolted the top half intake left the acc intact

your refering to the AAC valve right? controls idle...id suggest you take the whole thing off and clean it properly and put it back on.

[QWK32]

is there anyway you could have accidently damaged the solinoid or the electrical plug to it. the solinoid in the AAC valve is whats buzzing, i know they can do this if they are stuffed or don't have a good electrical connection. or if the pulse frequency isn't right, which could only change if you have an aftermarket ecu and changed it.

its defently the acc valve buzzing i cant realy see where but if i unplug it goes away

maybee it got bumped when i had the intake off while i was doing the fuel rail

Agreed. A mates SR AAC started buzzin after he removed/replaced the plenum a few times. A new unit did the same. Issue was dirty / dodgy plug.

the buzzing has quitend down

still there

i was wrong about the turbo timer it doesnt change weather its on acc or turbo timer

it sort of comes and goes

funny u here all sorts of strange shit when u havent driven it for a wile

been getting around in the missus bog stock vt

ever so slight
