Update:
Thanks for the quick responses. I have come up with a few more things. First off. To answer a couple of your questions.

The dump I got was not from a SDS and I did not get any fuel trim readings.
And I sprayed the cleaner directly into the throttle body without the breather tube in place.

When I replaced the plugs. plug tip on #1 was more corroded looking than the other 3 by far. (maybe misfire code?) Maybe I should look at replacing the plug ends. (#1 has just a wire on it, no coil sitting on top)

But another symptom that my C230 has had for at least 10,000 miles is that there was a BAD hesitation at around 4500 RPM when passing. (AMM?)

I saw the trick where you put the AMM in a plastic bag with rubbing alcohol and shake it and then dry it and reinstall. I tried it. Prior to doing that, the best I could get from my car was about 1000 RPM, after reinstall, I was able to drive around the block a couple of times at up to about 3500 RPM's with very little missing and actually almost drivable. Impossible before.

The CEL is still on and there is definately something wrong with the AMM. I am going to replace that tomorrow, and then see where I am. At least then I can respectably drive it to a mechanic with the proper diagnostic equip.

If I get it running halfway decent, should I attempt to disconnect the battery and clear the CEL before taking it to the shop? Or just leave it alone?

You guys have been very helpful.
