Hello, all... When working on my car today, I revved the engine from the throttle body to see if I could see the sleeves for the ports opening... however, the sleeves start to open as soon as its given throttle... isnt that too soon??? I thought there was supposed to be some kind of delay? Secondly... how to take them off and clean... Thanks for all the help...

 

sounds like they are plumbed wrong, as they should not even open unless there is a load on the engine.

 

damn

 

how are the plumbed up???

 

what do you mean plumbed up?

 

Is it wired/plumbed stock, or is there some sort of aftermarket config???

 

i never changed it since I had the car... and it looks stock to me...

 

S4??? S5???

then you may have clogged cats or some other exhaust obstruction

 

oh... what would be some of the other symptoms of clogged cats? i think I might possibly have an exhause leak... do you think that will cause it?

 

Nope... that would be the other way around.

Exhaust leak on a S4 = no aux port operation

I would confirm that it is plumbed to the air supply pipe coming from the cat... if it is, then you probably have a clogged up cat.

If it is not (like maybe the last owner plumbed it to the air pump) then it would cause the problem also
