I was taking my '98 Boxster (5spd) throttle body apart and cleaning the idle control valve today to try to 'cure' a sometimes erratic hunting idle and noticed the rubber sleeves holding the T plenum connector had a small port on

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I was taking my '98 Boxster (5spd) throttle body apart and cleaning the idle control valve today to try to 'cure' a sometimes erratic hunting idle and noticed the rubber sleeves holding the T plenum connector had a small port on each side. the right was connected to a small tube, but the left had no such tube. What do you do with the small hole of the left rubber sleeve? Is this the right part for the left side or did previous owner used 2 rights ? Do I plug it ? Does it matter ? Visible part # is PXO 416 410-1

POST 2Original post

Right side is SAI and should lead to a check valve. No idea about left side. Can't just be open. That may be your very issue!

Sorry what does SAI stand for ?

Secondary Air Injection. Start up feature that adds air with a small pump and reduces emissions.

POST 5Original post

It should go to a rubber Tee. One end of the tee goes back to the vacuum canister and switch under the manifold tubes between cylinders 1 and 2. The other end goes to a switch between the manifold tubes at cylinder 4 and 5. This one also branches over to the air damper butterfly on the front cross over tube.

POST 6Original post

Here is a photo from when I was rebuilding. I took this for someone else who had a similar problem. Note the White and Black check valve then tee.

This is a source reference. Confirm exact model applicability in the original material.
