2007 Honda Civic Si Misfire?

Hello,

I have a 2007 Honda Civic Si with an engine misfire. At idle, when the car is revved up to 2,500 rpms it is very bad. No engine light, but it is definitely misfiring. Had it at Honda they replaced the connector going to one of the coil packs. They said the problem was resolved, I've seen no improvement. While they had it they claimed the engine light came on for engine misfire but, it has never once be on for me. Also the misfire is very noticeable during cold starts, seems to get better as the engine warms up...

Thanks for your help!

Update:

Thanks for the response. I do not think it is in "limp mode", the check engine light is not on.
