Miss at high RPM

The check engine light came on in my 2007 GXP. I took it to the local Chevy dealer and they replaced the spark plugs with hotter ones. Now the engine misses at about 5000 RPM. I didn't notice the miss right away because I don't always "get on it" that much. Could it be the new spark plugs or do I have other issues?

It could be one of your coil packs:

Have you contacted the dealer who did the work to let them know about the issue? Please keep us updated on what they tell you and send a PM if you feel this isn't addressed correctly for you. I hope you're having a good holiday season in spite of the issue. Thank you.

Matt,

I didn't notice the miss until I was on my way up north to put the car away for winter. The car will come out of storage in April.

Is your problem solved? My problem was that the coil pack ignition ground wire was coming loose and eventually melted off then I just had to wire it back to the engine and all has been perfect since then.

It was 3 coil packs that were all bad. The car is back to normal and I'm happy.
