I have a 2004 with the T5 Engine with about 92K Miles, last week threw a fault code of a misfire in cylinder 2, checked out this forum and spoke with a tech (not for Volvo) friend of mine and discovered that a bad ignition coil is often the cause, I replaced the coil on #2 and all five spark plugs (also got an oil change which I'm told can now sometimes trigger this light), Light is still on, and the issue is this: at low RPM the engine rumbles and vibrates like a straight 8, once it gets up past 2500 RPM it smoothes out, but the power is still hesitant, and it is still throwing the same code. I'm trying to avoid going to the dealership, as I have some mechanical ability, (and money is also tight), any help would be great.
