Stalling Problems after CPS replacement
I had an issue with stalling and then a crank but no start so I did some research and learned the usual culprit is the Crankshaft Position Sensor. So I picked up a new one and put it in. It fixed the crank no start issue but now I can't rev past 2000 rpm without stalling. The car starts right up every time now but still throwing P0335 code after CPS replacement. What is causing my stalling?

Are you using a genuine MB CPS or aftermarket?
The factory CPS replacement service procedure details initialization via STAR/DAS following installation of the new sensor. However, when I did some searches everyone seemed to have no issue just swapping it out and running the car as is - except for those who <tried> an aftermarket sensor.
If you are using an aftermarket sensor, I would first try a genuine one. If that does not help or the sensor is an MB part, you may have to visit a dealer or Indy with SDS for the initialization
Check/clean the CPS connection again as well

stalling no start even with new crank position sensor
Hey guys I found the culprit on this 05 e320 i had a car come in with no start and got p0335 cps code and replaced the cps. Next day car came back in with no start again. i retraced the wire and found no problem then as i moved the connector as the car is cranked it will sometime start or wont start i looked at the inside of the connector and that female spade is wider then it seems I bend the tabs closer together with a pocket pick and it starts everytime.
