Lightbulb Gibson Manifold and check engine light

Hi guys,

First post for me, you have an awesome forum going on.
I installed (with help a new Gibson 6 to 1 manifold yesterday after driving with a cracked one for about 2 years. (yes I know it is not great)
It sounds much better, only problem is my check engine light went on and I have to get smog this month. The crack didn't set off the light, but this new manifold that should let it exhale better did. I disconnected the battery hoping to reset the computer, but have to wait till after work to check. I also know my PCV valve is bad, but have no idea if that could cause a problem.(getting a new one today).
Anyway, does anyone have an idea what could be wrong? I am a novice to working on cars, but not to overcharging shops, so bear with me please if I don't get it all

I should have thought of it... error code 21, just replaced the O2 sensor and bingo, purrs like a cat.
Well a cat with a slight lifter tap that is

Thanks again!
