Seems to have a slight miss
No big problems. No codes. Maybe I am just being paranoid!
Car 2003 Z06 with 8500 miles and it seems to have a slight miss at idle. Can't tell under acceleration for sure - but no defenite miss like a bad coil pack. Have had that on another car so I know that one!
Recent history - installed AR Headers but did not change plugs/wires. Didn't think they needed to be changed. No light show at night either!
When I first fired up after header install pass. side coil pack was accidentily disconnected. Was rough running so I shut down. Seemed fine after that.
Any suggestions? Change plugs/wires now? Could coil pack being disconnected for short time hurt anything?

There is a chance you fouled a plug. Remove that plug and see if it is fouled. If it is clean it and put it back in. I had the same problem on my (LIGHTNING).

Check the plugs and the wires. If they are ok, use a timing light to make sure the coils are firing on a steady beat. We have found in the past a coil can misfire and NOT throw a code indicating a coil problem.
