I need a new "CPS" from what I can tell the '98 c280 used 2 diffrent ones?? How do I tell which one of the above sensors is the correct one. Where do I find my engine #? (I'm guessing that "Engine: -30 370998 & Engine: -30 370998" are engine #'s because it's not even close to my vin#. Thanks in advance.............ps I'm talking about the sensor that is located on the back of the engine near the tranny bell housing. Car intermittantly dying/ and intermittantly not starting etc........
