I pulled # 5 and #20 fuses, let the car sit for over an hr and installed them. Started up the car and it ran fine, took off for a drive and all the sudden my stability control light comes on and the car starts misfiring. I turn around and get home asap. After reading the codes, Im seeing random misfire P0300 which turned into P0308 #8 misfire. I pull the plug and it looks a little rough along with the rest. After a new set of NGK plugs, the car is still misfiring and giving me a P0308 code.
After that, I tried switching the wires (MSD 8.5mm) from #8 to #2 to see if the misfire jumps to #2 cylinder but instead I get a P02548 code along with the P0308. Im at a loss right now, so I pulled the two 5 and 20 fuses and disconnected the battery.
What could have happened already since the car seemed to be running fine the day before, besides me messing with it.
Any help would be great!

Which NGK plus and what gap?
Did you use Never Seize on the plugs?
Never Seize is a conductor and can short a spark plug if it gets on the center electrode or porcelin.
Do you have any stock wires you can test with?
