Check Engine Light is back!
I then placed the cap back on and connected the OBDll reader and it passed! I drove the car to work this morning to make sure it doesn't come back and so far so good! I think that's all it was.....and just to think, a Mercedes-Benz shop near my home wanted to charge me $100 bucks for a diagnostic test and $275 to replace 2 O2 sensors (If this was the issue and that's for the labor only)
The $140 bucks I paid for the OBD reader is a bit much but It is well worth the investment. Thanks guy's for your input. http://harborfreight.com/
might save someone a few bucks in the future
