IACV Mesh Screen broken?

[Ryuzaki]

So I went to clean my IACV today as I'd been experiencing fluctuating idle to find this:



Is this a problem? Is this why my idle is rough?

[dougie_504]

ably idling because not enough air is getting through due to the carbon build-up, and the hole won't help. Buy a new seal.

[Ryuzaki]

What exactly am I looking to buy?

[dougie_504]

IACV seal/gasket. Take it with you, tell them what engine it's from and show them. Confirm it's the right one before you pay/leave.

And clean it out with 'Super engine conditioner' or 'Suburu upper engine cleaner' (same thing)

[dougie_504]

beeza, haven't seen you in ages!

Is Subaru UEC so much different to regular carby cleaner?

[TbM]

Subaru upper engine cleaner is much better at removing carbon build up compared to the regular carby/throttle body cleaner you get from supercheap/repco etc. Its got a different combo of ingredients that seem to work well and it comes out like a foam rather than the usual spray. Usually get mine from the local subaru service/parts centre for about $17, the cans are small but you dont need to use as much so it balances out.

^^ Exactly!

Hi Dougie

Don't get on here much but I miss it and will propably get back to talkin' shiz with da boys real soon I reckon! hehehe

When U use the cleaner,give it time to soak in and it works so well.Same when U use it in the upper engine,ya gotta give it time to soak in.
