You have to check your air filter, the mercedes are sensitive to air ratio.

Ok there is a number of things that will stop it from revving past 3k from your description I would check the ignition timing for advance mechanical and vacuum .I don't know when you experience the fault or eg while driving or just free reviving in Neutral .
BTW 190e does not have limp home mode so there is a real problem. Hope this helps

You must be having a check engine light or maintenance coming up on the dashboard, if yes the best way to start troubleshooting this problem is to run a diagnostic test on the vehicle.Also after changing the mass air flow meter did you reset the ECM ?If not then this is required after any repair you do.Hope this helps.

My 1992 190E(1.8) has recently been to 3 garages


You could have 2 problems. The hard start in the AM could be a bad fuel accumulator and or check valve in the fuel pump. The engine cutting out could be a bad idle stabilization valve, dirty throttle body and housing or a bad 02 sensor, could also be just a CO adjustment. Where are you located?

My wife has had an issue with her 06 dodge caravan that once she puts gas in and goes to take off it stalls and looses power. When I try to rev my engine all it does is go to 3000 RPM and then it sputters...


Greetings, assuming the fuel tank was contaminated enough to cause the fuel filter to become partially obstructed, it would not be good advice to install Techron fuel treatment or any other fuel treatment after installing a new fuel filter as doing so would could very well contaminate the new filter and / or new fuel pump. The vehicle in question has an engine rev limiter while the transmission is in park or neutral so the 2600 - 3000 and sputter are normal which is the rev limiter kicking in. There is not enough information in the complaint to determine if a new fuel filter and fuel pump are justified or not. Personally, I would inspect the plus (+) power lead to the fuel pump first with a volt meter to see if you are getting at least 12.7 volts and if you are, then remove the fuel filter from the fuel tank and inspect before purchasing a new filter. I would test the fuel pump for correct pressure if I found the fuel filter to be fairly clean and correct voltage to the pump. It is not good advice to buy parts before you know what the true problem is.

Drivers authorisation system on mercedes


My car is a 1.8 - E 190 , 1993 model. The car is in a good condiction and done only 93,000 miles. It never gave me any problems up to now and for that reason I love it. The problem developed last week is that, it is difficult to start and when it starts sometimes it does not rev up and the engine cuts off. The ignition side is OK with new spark plugs, rotor arm and adistributer head. The hi-tension leads seems OK. I sort advise from people with Merc knowledge. There suggestion is perhaps it is the malfunctioning of the fuel pump relay. I have difficulty in locating this part. Can anyone please advice me how to overcome this problem and the location of the fuel pump relay. I am a professional Mecanical Engineer with reasonable knowledge in car mechanics.
