Saab/2007 saab 9-3
when i am driving at a steady speed, the turbo is moving up a down by itself, like sputtering..... also when i am at the stop light, sometimes the tubro dosent work, but the rpm is still going up, but no power? i have changed the turbo boost valve......
still doing it.
I am sorry, but as noted in my profile, my hands on experience is limited to the older non turbo 900s only. I can however recommend a very comprehensive online source of data ($25/year/vehicle), but well worth it at <www.alldatadiy.com>.
Hope this helps,
