Are there any symptoms to look for if I suspect a bad coil pack? My '04 has about 125K on it and has had about 8 start failures over the past few months. When the key is turned and released, the car fails to start until the second attempt. No codes showing. Also when cruising along, there is a noticeable surge, not related to the a/c compressor kicking on and off. Just did a full tune up at 90K. Suggestions?
Thanks.

when my coils started to go I would get a pretty heavy shutter when accelerating hard.
I was also experiencing starting issue similar to what you mentioned, but I related those to the age of the battery; and they've gone away once I put the new battery in.Thor - 2004 XC70 (225k and going strong!)

A bad pack shouldn't affect overall starting like a single old school coil would.
I would say your problem lies on the fuel delivery side, starting with a nearly clogged fuel filter.
