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

Hi there,i have a c200 elegance 2005,i seem to be having problem after problem and my pride and joy is becoming a money pit!! well here goes,it wont rev past 3000 revs, i was told this would be the mass...


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?

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.

IT IDLES HIGH AN WONT REV UP


Change all the filters (fuel and air). check and see if all your spark plugs are firing or just change them. if it is fuel injected make sure your injectors are working. Hope something there helps get it running good.
