Testing Coil packs; 1999 S70

[Generic1]

Hey Mike, just wanted to follow up on this thread (I know it's 2 years old, but...)

I have a 99 V70 XC and I am dealing with a misfire in cylinder 4 as well...

I have changed the coil and plugs, with no improvement in the misfire...

I haven't checked for a stuck valve or the injector yet (getting ready to..)

I DO have etm issues (light comes on, with it bogging down while driving.. drives ok, but feels very weak)

The misfire is very new problem, thought it was bad tank of fuel... changed filter, added some additives, etc, but still persists. I wondered if fixing the etm worked for you, or what the solution was? Thanks!! John
