Default misfire

Agreed if its throwing a misfire code plugs and wires is always the logical start.

Sounds like a heat-related issue? Does the shop suspect the ignition control module?

Thanks for all the suggestions. Finally yelled at the mechanic enough so that he brought it to a Pontiac dealer and it was fixed in about 20 mins. MAF sensor had a bad connection. This was after the first mechanic had already tried throwing a bunch of new parts at it hoping to fix it. The good news is that I now have new plugs, crank sensor, fuel pump, fuel filter, and a bunch of other parts that I can't remember off the top of my head, and at no cost to me! The bad part is that i was without my car for 3 weeks.

Before I read the solution, I was leaning towards a coil pack. They can fail as they warm up, but most places check them cold, and they're fine. Glad you got her back!
