Well I am still dealing with the CPS. Advanced Auto part got my car running, however a heavy foot or hitting 80mph/3000rpm makes the car jolt to a stall and the CPS CEL is turned on. (this happen to anybody else? I havent read these symptoms from anyone else) Recently its taking a min to turn over, and i know what that means! Times ticking away!! I believe since its not a Bosch part, when I really put the sensor to the test, its failing on me. So my question is where do I get this part option A the Autohaus website, first post of this thread? Benz dealership (2 sensor options? quoted at 150 & 90$), or and LOLLL, the dealership at 198. interestingly, the dealership told me this was part number 5080350 & a google search shows me this is for a Wells part, not Bosch... HMMM.
