Stalling Quiz: WINNER GETS $50
What is your best guess? Winner gets $50
Car: 1988 190E 2.3 8V Problem: stalls at a stop or while slowing down to a stop (All random) Parts replaced: 1. Fuel pump 2. Fuel filter 3. Fuel Pressure Regulator 4. Fuel accumulator 5. ICV 6. ICV hoses 7. Air meter rubber boot 8. Crank position sensor 9. Fuel pump relay 10. OVP 11. Temperature sensor 12. O2 sensor 13. Catalytic converter 14. Exhaust 15. Resonator 16. Spark plugs 17. Ignition wires 18. Ignition rotor 19. Ignition cap 20. Battery 21. Voltage regulator 22. Breather hose 23. Breather hose coupling 24. Fuel cap 25 EHA washers What was done: Adjusted EHA and Lambda Checked fuel pressure Checked fuel flow for each injector Checked main fuel flow and quantity Air plate adjusted If your suggestion fixes the problem then you will get $50. So far this problem has lasted one year and not a single suggestion from any of the forums has provided a solution that eliminated this stalling. Rules: You must state step by step the procedure that you would undertake. It must be replicated by an idiot like me and will not require that I end up in the hospital. In addition, replacing the whole engine or complete systems are not acceptable solutions. You must pinpoint a specific problem, support it then list and describe exactly how you would go about it. Before I implement your solution it must be vetted. Once I agree to go with your solution there will be a testing period of two weeks before I declare you a winner. Note: This competition is listed in several forums I reserve the right to terminate this competition at will Last edited by professor; 06-06-2009 at 09:24 PM. |

To help you get an idea of all the details here is a thread in another forum on this problem:

the speed sensor in the gauge cluster is loose or dead. very common on the 201s and 124s. good luck, chuck.

I had removed my cluster to fix the odometer, so I am fine with removing the cluster to check. Where would the speed sensor be? What will it look like? Why would it contribute to stalling?

The Hall effect sensor is attached to the rear of the speedo unit, left of the speedo cable connection.

I thought that the Hall effect sensor is the crank position sensor and that is attached to the EZL. I replaced the crank position sensor already.

Hall effect unit in position as per blue arrow.
![]() Heres the back of the speedo with the Hall effect doover fitted ![]() Have you had the air mass and the fuel distributor off and cleaned up? The air plate could be sticking. Last edited by whunter; 07-09-2012 at 06:50 PM. |

I did however learn something about how it picks up the spinning of a disk and turns it into a signal. Pretty nifty! |

Yes, I had those off and cleaned. I even replaced the rubber boot and adjusted the air plate with .05mm clearance all around. The fuel distributor has been tested for flow on all outlets. I also have a spare one and when installed the car still stalled randomly as it does now.
What you're describing in the photo is attached to the speedo/trip meter. I have a spare one and will compare. |

So how about this little beastie?

I would suspect the fuel computer.
Do not want the $50, you've spend enough already. |

Throttle control - always a suspect.

I checked that and compared to another unit just to make sure. They both gave the same readings off line and while in the car. Statistically that means they are fine.

A new car will solve the problem.
