Here is what it was doing....
I was driving it with the wife one day all over town and the country side slowly and at low RPM’s. After a few hours of this we ended up in the city and had to stop for a light, when I stopped, it stalled and would not idle.
I got it home by keeping my foot on the pedal. When I started it, the dash would read "SYS".... and it ran rich, and the engine would not idle at all There were no codes..., just says “Service Engine Soon”, that is the freaky thing. Scan tool reads all is well on every point, fuel trim was on, timing was on, all was reading well….. That is what was throwing me. The manual said that the “SYS” meant that the CCM "Central Control Module” was bad and needed to be replaced. That’s why I was looking for info on replacing it.
My wife read in the manual about cleaning the Oxygen sensor when the engine was running like crap at idle….
It said to clean the o2 sensor by running the engine at 2 grand for 2 minutes. So…. to appease my wife, I did it and it fixed the problem. (Good thing!)
I guess I cannot drive the car slowly at low RPM for long periods of time. It must have started when I drove the car in a parade last summer and then never really cleaned it out....
I will be changing all the o2 sensors real soon!
Thanx for the help!

You posted two different symptoms, did it display SES or SYS? SYS will often display with a low battery, I would make sure yours has clean connections and is fully charged first, good luck.

What shape are your ignition wires in? Got more than 60,000 miles on 'em? A bad plug or coil wire can make these HEI-equipped cars shake, buck, and misfire like a ****, too.
