Hi all,

I got a 02 9-3SE 2.0HO Engine with Turbo.
While I drive on the road, on red lights, after a while the turbo meter starts fluctuating and so does the RPM meter while I have my legs on brake paddle. And I can hear some pumping noise as well as car shakes like it is ready to move.

Does anyone have similar experience? Anyone knows the cause of it?

Thanks,
Roger

 

could be a vacuum leak

 

Geez u r awesome! I didn't find much problem after a while, then yesterday the check engine light up. I took it back to Saab for repair. It found the vacuum leak and replaced valve.

Check engine code P1110

It said "found valve not holding vacuum"
