Bad Idle (gonna fix this once and for all)
and before Bandit screams "fuel pressure" , I'm just trying to eliminate the simple things, and this is why I ask:
I have:
Cracked Manis (badly)
AND
Bad alternator bearings
Which I know contribute to KR. So, can it?

well if the exhaust is Loud enought for the Nock sensor to pick it up at idle im sure t can make it not run right.
also If there is Clean air getting in at idle it can mess up the O2 readings and make the PCM adjust the Air Fuel mis Wrong

I think it'* his cat. I rode in the car on the freeway and on hard accelerations. I could distinctly smell rotten eggs driving on the freeway and after a couple hard runs, also when he pulled away when he left to go home, I got a strong whiff of it. Also his EMs are VERY cracked, as when we did the seafoam, we had smoke barreling out from under the hood when we started it.

I disagree. There isn't enough gasses flowing at idle for it to have an effect. My car purred like a kitten at idle with horribly cracked manifolds.
Poor idle is either ignition related or a vacuum leak typically. Or a dirty TB.

TB has been cleaned, Ignition has been checked, Vacuum lines have NOT been checked, and it seems like that could be the issue, since I'm not running rich or lean (I don't think) and I've taken them off so many times. I'll get a pressure tester and I'll see what I find
