intake manifold 2nd venturi question
I know Im not using the correct name etc..
but the secondary flap you may call it thats inside the intake manifold I have a question about. What operates it ? vaccum or electronic ? from time to time I get a bog on my car when giving it alot of throttle, almost even like a flat spot.. I was going to check the TPS sensor voltage first and then look into the other area. Anyone who can shed lite on this apparatus and exactly what it works off of etc and when, Id appreciate it. thanks Dayle

You mean the IRIS valve? The big one that closes off the two halves of the intake?

P.S. Check the TPS for erratic operation as well as preset voltage, particularly in full throttle area. Refer to my notes in the how too section.

Dayle, there is a one way check valve under the intake manifold, behind the alternator that can crack or fail from age or heat.
The under manifold hoses get brittle with time and heat. Check and replace them as necessary. http://www.subaru-svx.net/photos/use...svxfiles|24710
