Having shifting problems? Feeling sluggish? Misfires?
Replace the friggin MAF!

I was having a bouncy engage and misfiring if I push the accelerator more than 50%...I could only go above 80 if I did it gradually.

and now, SNAP.. there is the SLK I fell in love with. Its like having a significant other drop 25 pounds, get abs and understand what you really want. all overnight.

heed my advice, all ye 230 owners of old...

RE: about 121,000 miles on when it SHOULD have been changed

The electronic control in hot film mass air flow sensor controls the temperature of the heating resistor (RH) by means of a variable voltage, so that its temperature is 160 °C above the intake air temperature detected by the temperature resistor (RL). The temperature of the heating resistor (RH) is detected by the sensor resistor (RS).

If a temperature change occurs as a result of an increased or reduced air flow, the electronic control corrects the voltage at the heating resistor (RH) until the temperature difference is again achieved. This control voltage is used by the engine control module as a measure for the metered air mass.
The intake air temperature is detected by a further NTC resistor.
