Uggghh why me!
OK First off when i floor it on my wife's C230K on a corner it starts to misfire I turn it off and then it acts like nothing happen.... Also all the gauges will turn off and the electronics wont work i turn it off then everything works but the car wont start unless I move the negative cable around but its on there tight.... Then when it rains/wash my car it starts to have a foul smell but i don't see water anywhere?!?!?! 
... Well then last but not least when is it recommended to do the water pump and do a Diff fluid flush? Neither pump or Diff flush has been done... Ive done thermostat 1 ignition coil CTS (Coolant temp sensor) Radiator Flush oil change Air filter and fuel filter all were OEM still with 120K miles on it 
thats what i felt like doing to my father in law because 0 maintenance was done..

Is there any corrosion on the battery terminals ?. Sounds as if there could be some on your negative terminal.
I suggest washing the battery & terminals in a weak solution of sodium Bi Carb ( baking soda) which will neutralise any acid from the battery. You will see it foam up as it neutralises the acid.
Next I would remove the terminals & scrape off any build up between the battery post & terminals.
After refitting, coat the terminals with a little vaseline to prevent further corrosion .
Be sure to remove ignition key before removing battery terminals to avoid frying your SAMS.
Remember, remove negative first & replace negative last. http://7faq.com/owbase/ow.asp?GoodEn...tingTheBattery
How old is the battery ? .They seem to fail after about 8 years . These cars need a battery
in good condition & the correct amp/ capacity other wise strange happennings can occur.Your local battery store or auto electrician can load test the battery & test alternator output.
Good luck & your feed back is welcome.

Was that corner a left or right,...
Check to see if you have water drainage clog,.... both corner of engine bay against firewall,... where battery sits (passenger side),... and other where FrontSAM is (driver side),.... Flooded compartment there might also contribute to the foul smell as well,...

Your battery might have a loose negative terminal or the earth cable might not be making a good connection with the body.

Look at it carefully. The battery post itself might be loose in the battery & not making a proper internal connection. It happens from time to time.
