    In the morning the car starts and as I drive, the speed power gets lower sometimes. So I stop the car and start it again, sometimes up to 4 times a morning , then it drives fine.

    Today it also did this to me in the afternoon and had no speed power. None of the lights are on.

    What is the problem?

    I assume you are choke-hunting in response to a cold-start issue? Mercedes-Benz has not used a mechanical (driver-actuated) choke in their vehicles for some time, I believe. It used to be a knob with a symbol that looked like a flap pivoting in an aperture.



    Your 1999 should limit air flow (choke,) or richen the fuel mixture without your input. Let me know what your symptom/concern entails.

The air flow is not restricted to richen the mixture, the fuel injector pulse weith is adjusted for more fuel flow based on coolant temp, air charge temp and barometric pressure, so much mis-information out there. I think your problem may be a failing fuel pump.

I wanna know if the 1985 mustang gt 5.0 ho is electric choke or manual choke


Electric choke from the factory,the choke pull off runs off of power from the alternators stator post which supplies about 7 volts when its running.Spring tension and a stomp on the throttle set it.

Flooding,black smoke,run hard,choke sticking


The first thing i would look at here is the choke pull. Make sure that after the car starts, the choke props open. Also, as the engine warms, make sure the electric choke is opening up. If not, make sure you have 12V to the choke. If so, replace it. This should solve the problem.

But let me know if you need any further assistance, ok? We'll get it working! :)

My Mercedes Benz c200 automatic choke has suddenly stopped and the car stalls when trying to select drive until the engine is warm but once warm the engine is fine so there are no problems with the idler...


Check the Air Intake Temperature sensor, that is used by the control module to determine when to start and stop the choke. The AIT is mounted on the air intake.

2001 mercedes c240 has a really rough start but when the car almost dies I turn the car off wait 3 seconds and it starts perfect. Next comes the issue with having to warm it up before driving anywhere...


Gasoline- thank you. Warm up is not an issue like diesel is. Sounds like the choke is is either wide open or over choking. With the engine cold, remove the air cleaner and note where the plate is at the opening of the carb. If it is wide open then without touching anything else and engine not running, step down on the gas pedal and see if the choke plate reset itself to restricter the carb inlet. If it didn't, then take some WD 40 and spray the linkages and the rod ends holdin the choke plate.By hand work the plate and linkage holding the gas open at the carb. Then set the plate to wide open and do the gas pedal thing agan to see if choke sets itself back to restricting the carb intake. If it does, start the engine and as the engine warms upm the choke plate should start opening on its own and you are off and running. Roitine question. Is your air cleaner clean? If the choke plate needs adjusting. get back to me. K? Good luck Remember to press the gas pedal down once before cranking. That sets the choke for cold start. Hope this helped you Good luck Note, the WD40 won't hurt anything but avoid spraying with engine running or when engine is hot..

1998 C180 Sport Automatic choke faulty


If it's fuel injection I don't think it will have a choke. It will have what they call an Idle Air Bypass valve or something of that nature. If you can find it take it off and spay Carb cleaner through it. Be carefull not to get it in your eyes. I'll do some research and see if I can find a photo for you. A lot of the time they get dirty and just need a good cleaning.
