So just to report back, I changed out all 8 plugs with ACDelco 41-110 and ACDelco 748UU wires from AutoZone. As suggested, I also swapped coil #7 and #3 in case the miss returned I would know if it was the coil or if it was something else. Even though the plugs had 10 years on them, I think taking the 2nd battery tray off to get to the coil bolt I dropped thru the hole in it accidently when I was swapping coils took longer than doing the entire driver's side plug and wire change. Passenger side obviously took longer but removing the airfilter and it's entire housing helped open up the area to reach in from the front to get your arm in there while standing on a milk crate.
One thing I noticed is right below the threaded stud to the left of coil #8 towards the firewall, there was a slight drip of antifreeze. I noticed it because a drip hit my hand while trying to get #8 out. it must not be hitting the header or I would smell it burning. Not really seeing any large loss quickly in antifreeze either (knock on wood). Any idea what is in that area which could be dripping?
