A few weeks after my header install my car ran like crap and gave miss fire codes. Problem was traced back to a bad plug wire.

We need more info like WS6 stated.

Any SES light, is it flashing?
Any codes?
Installed the O2 sensors and plugged them back in correctly?
Any leaks around the header flange that would be causing your O2's to go screwy?
Checked all of the plugs and plug wires?
