Hi guys
Looks like I have troubless with my avac. When I rev the engine diaphragms moves up and stay up. I know that they shoul move up when rev and move down when on idlle. But mine want move down. Iw tryed test diaphragms with mouth and they work well. iw tryed to disconect line wich is going from electro valve to diaphragmas and car goes bad at low rpm but from 5000-7000 goes sick, when I conect everyting like it should be car goes well from 3000-5000 but after is dead. When I disconect conector which is going from ecu to electro valve car goes well only from 5000-7000rpm .
Here is vid how they should work http://smg.photobucket.com/albums/v214/ ... _A0015.flv

Does anyone know what is problem


TNX a lot

So when you rev they move, and when it falls to idle they wont move back?

BTW both your links dont work.

links repaired,yep here is video

I think the vacuumhoses at the electric solenoid aren't installed correctly. So switch those 2 hoses and check.

tnx a lot man that was problem

If i rev the engine the diaphragms will moves up and down normally. Is the ACAV systeme ok?? Anything else to check?

They should move again @ 5k RPM.

Thanks you, i will check it
