T/C & Missfires???
I installed T/C about a week ago and got a SES light a day or 2 later. I played around with my HPP3, which cleared the code (i guess). Drove it a little more and parked it for a few days. Started it up today and got the SES light again at idle. Noticed the idle was a little rough, so I went to Auto Zone and had the codes pulled. Sure enough multiple cylinder random missfires (P0300, don't remember for sure). I'm thinking maybe this has something to do with the lighter load at idle?? Do I need a higher idle or have somethings deleted from my pcm?? Anyone else had this problem?

The lighter mass can effect idle. I'd try turning the idle set screw on your throttle body about a 1/2 turn open and see if a little more air helps it out.
I would also reset the computer (disconnect the battery or pull the PCM fuses) and do a proper idle relearn. Sometimes that is enough to solve it too.
Also I would check your plugs. The platnium can come off and one may be bad.
