i have only put 25k on the car since i bought it 4 years ago and i know i replaced them the first year i got the car it so mine should still be good at least i hope

 

But like I said, they were updated again. It's worth checking them. Newest update is 2008 I believe. Most common symptom for 01 coil packs is sputtering or misfiring under boost and usually gets more noticeable when the engine warms up to full operating temp and begins to heat up the coil packs.

Try logging blocks 015 and 016. I think those are the misfire counters. Whichever one is highest is usually the problem cylinder. Swap the coil packs around and see if the issue follows the coil packs.
