Crankshaft position sensor failing?

How can you tell when the Crankshaft position sensor is failing?

I know it is a common problem and I don't want to get stranded. Lately noticed that when I start the car when it is warm the car sputters a bit upon start. It seems the sputter is longer when the car has been driven fairly hard and I pop in to a store and come back and restart the car shortly after parking it.

I've got 128k miles on my C55. I'm not sure if the sensor has ever been done.

I had one in a CLK55 act up after getting hot and would not start. Cooled down and would start.

Put one in before it leaves you stranded.

Yeah, I just threw one in today. Not the hardest thing to do, but still took me an hour due to the location.

I did not have any codes pending, but as you said...better safe then sorry.

True, cheap insurance.
