Yo!
I need to re-new these parts i think as my car is doing wierd things.
I have pics below with 1,2 and 3 parts on it please see pic.
part 1 came from the metal tube where the air filter joins on to.
part 2 came from opposite where the idle control valve goes.
part 3 came from right under the idle control valve.

All are from around where the air filter joins on (or induction kit).
