9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
I have an 07 9-3 Aero with approx 59k miles on it. It initially started with a "hiccup" every once in a while. Over time, the feeling has changed, and it feels closer to a misfiring. I have not gotten a CEL to date, so I can't be sure.
So my question is...is there a way to test the coils...
