OK. So I got under the car and it appears the #8 spark plug wasn't quite seated correctly and was a little detached. I guess it was in enough to work and wiggled a little loose. So, after 20 minutes, a cut up arm, and crawling on top of my engine I managed to reseat it and seems to be running a lot better now. Personally, it still doesn't purr like it used to, but have no idea what the issue is exactly since the coil, spark plugs, wires, opti, and alternator have been replaced. Running out of ideas. Wish someone had a trans am near me to compare and see if there is an issue or im just crazy.
