9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
Scrolling thru the threads, I have found similar circumstances; however, none are quite like mine.
2007 9-3 Aero 2.8t V6, 126K for mileage.
I have brand new OEM coils and plugs.
The tach stays nice and smooth and the engine is smooth, no bucking or stuttering at all.
