View Full Version : Fitted new air filter, high idle

26-05-2007, 12:18
My mechanical knowledge is somewhat limited but i had a bash at fitting a K&N which went surprisingly smoothly untill i started the car up. When i started it up and sat there for a few minutes, it was idling at 2200. Im guessing this may be something to do with the breather pipes as these are still not connected?! Would they make a difference to the idle speed? Would i need to buy breather filters for both of the pipes? Car is a Willy1 btw, any help greatfully received!

thought the breather pipes fitted in the base of the k+n

they are supposed to but the pipes are too thick and wont fit or reach. :?

still they shouldn,t affect the idle speed really unless your getting dirt in and blocking the isvc valve up.

I might just go and have a mess with the ISCV then, my mate said that is the most likely cause and its just coincidence that the idle changed when i put the filter on.
