What did tightening them do to the idle? And more specifically, how did it change your AFRs?

I wouldn't change the coil until you see what tightening those bolts did to your issues. One fix at a time and test in between each change.
Thanks for the response. To get to that bolt; I will have to remove the entire sensor plate assembly manifold. Not sure if it is worth the effort or will make any difference now that all the other bolts are properly torqued. I haven't put everything back together yet; don't know what affect this will have.

When I installed new plugs the old ones were very wet. This leads me to believe the lack of a proper hot enough spark resulted from a weak coil output. Excessive air, caused by the leaking intake, would have resulted in a lean dry spark plug condition.
