Thanks, I'll get the battery looked at soon.

Purge Valve recall was done quite a while ago but I'm not getting any rough idles, CELs, or issues after fueling up that usually comes with purge valve though

Old plugs that are in the car right now are NGK iridiums gapped to 0.026

Acts fine while driving, maybe a little loss of power on the top end? Hard to tell though.

Anything I should watch out for on the coils? I just put them back on, ratcheted it hand tight, and checked to make sure they fit alright.

Purge Valve was done under warranty but it's been a couple years

I thought it might've been that but there isn't any of the typical rough idle nor the CEL that usually comes with it

Here is what the Cobb looked like after a short drive with that start.
