I've got a '97 9000 Aero, which I discerned, with the guidance of the helpful people on this board, was suffering from a DI casette failure. Not having quite the technical know-how to fix it myself, I took it into the local Saab dealer. I told them I was having problems with acceleration, which was problem from a problem with the direct ignition casette.

Took it into the dealer, and sure enough, they diagnose it will having a failed DI casette and blown spark plugs. They also found a problem with the exhaust while working on it. I should have been a little more careful when the guy said "Saab's OEM exhaust system is ridiculously expensive, we'll just use an aftermarket one."

So, today, after a considerable amount of cash dropped for the repairs, I get the car back. And it is twice as bad as when I brought it in. Its got a new DI casette and new spark plugs, so the stuttering is no longer there during acceleration. HOWEVER- now the car will not go above base boost, at all.. it stops right near the beginning of the yellow section of the boost gauge as if it is hitting a brick wall. Plus, the g'damn exhaust system they "fixed" now has a noticeable rumble even at low speeds in the cabin with all windows closed.

Sorry for the long-winded post, it's just that I am frustrated after putting money into this that it comes back worse than before-I need to learn to do my own repairs, soon. But.. I was hoping you all might be able to at least help me diagnose the base boost problem. It has never happened before, so it was something the mechanics did that tripped it. Any ideas of what happened or how to fix it? Thanks so much

A very distressed Saab owner..
