Hello Saab municipality, since I am quite new in the sector Saab I urgently need advice! I have been driving a Saab 9000 Aero Bj.96 261000km with Nordic kit should have about 275Ps?! (hears good!) but now comes my problem, I have changed almost everything(damper/springs/brakes/covers/customer service was made/new APC valve/ etc.)though it would make sense?!)) but somehow he doesn’t want to!? he stutters from about 1500U/min. at full acceleration(if he is warm) he stutters even more, and absolutely does not get into the gears! again and again performance suspender. what could that be? my nearest Saab dealer is 1h away and he could only tell me by phone,possibly Zünkassette?! Ask for your help does not want to buy and exchange unnecessary parts! P.S. lives room Esslingen near Stuttgart
