My 2008 SAAB 93 2. 0t has intake valve failures. In the morning it idles rough until it warms up; this has been verified by a SAAB specialist. My engine is not modded or altered in anyway other than the consumables over time (belts and such). A quick check for 2008 SAAB vslve problem leads to forums chalk full of other owners with the same issue. Gm should foot the bill for this $2500+ rebuild of the engine that they poorly manufactured in the first place.
