Question about 1985 Mercedes-Benz 190

Open Question

I have a 1985 190e Mercedes gas engine. it starts right up but starts idling rough and shuts right off. i try to restart it and it will keep doing the same thing until it gets warmed up a little and idles rough until it it almost at operating temp. if you try to touch the gas pedal it shuts off or runs worse until warmed up. it has a little idle miss when warmed up but runs good down the road after warmed up but after about 3 miles it acts like it runs out of gas and shuts off. when you turn the key off and try to start it it starts right back up like nothing ever happened. i replaced the fuel pump,fuel filter, the fuel distributor and electromagnetic fuel controller. i drained and cleaned the gas tank and gas sock.my speedometer and odometer don't work and the overload relay fuse blows when i replace it. can anyone help me out by telling me what the problem????????

This sounds like the throttle positioning sensor (TPS) is going out. Could also be a bad O2 sensor or partially blocked EGR valve. Start with the TPS, then got to the O2 and EGR.

Thanks,

SOURCE: 1985 944 porsche speedometer stop working

There is a gear in the speedo that breaks. This is plastic gear on a metal shaft. The last fix I did was to remove speedo and open it up. I super glued the cracked gear to the shaft because I was unable to find a new one. It worked again with no future problems. I hope this helps.

Hi, Joe here The problem sounds like a faulty crankshaft position sensor. The sensor is located on the transmission bell housing on the left side. Can be accessed threw the top of the engine near the firewall.

Does it have any power when you start moving? I've seen a lot of plugged catalytic converters. You may want to have an exhaust back-pressure test done.

1996 mercedes c280 dies when put in drive


Engine stalls or RPM fluctuates at idle up and down or dies near idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

1988 Mercedes Benz 300E 3.0L Gasoline F.I. ''Sputtering at Idle


ok..you must have more than one car???? you don't drive the 300 atall im guessing. #1 start car drive up the road and \back to your house. #2 let it idle till problem starts. #3 once it does start with the problem keep it alive with the gas pedal. #4 once your have it safely from dying in higher rpms "rev it" like a kid would, you know like if you were gonna race some one lol. be careful not to over rev or damage engine. you should do this for five minutes no longer than that. #5 let it idle for another 5 minutes. #6 repeat every day until problem with idling decipates. it took mine 3 300e like 3 days of this. if your not going to drive the car once you get the problem out of the way. turn the car on everyday and let it idle for 5 minutes atleast and take it for a short drive once a week. they get lonelly you know lol. later on you can just turn the car on every 2 -3 days and let it idle but still take it on a short drive atleast once a week

1994 camry 4cyl. was running great. drove it to work and shut it off, then went to start it back up and it shut right off, wont idle. I can keep it running by keeping my foot on gas and its not running...


have your idle control switch check, easy and inexpensive to replace. The idle control switch is what keep the engine stay idle. also have your throttle body clean by a professional having that many miles, it will give you better gas mileage.

Engine wont idle unless you keep your foot on the gas pedal


First, try a new accelerator pump. They're less than $10 and easy to install. On the side of the carburator, near the linkage. It's simple a small rubber diaphragm.

Car idles low, stalls after start


Common issue at the shop (i'm a ford technician), here is what I do to correct it.
Here is the most common cause of surges and stalls at stops and low erratic idle speed and rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
