Check engine light is on and the engine is shaking

I mean by specification that about wire material and its resistance and cross section area of it and every thing concerns about electric current and voltage since it is an electric part of the car

I have oil much leaking at the two camshaft sensors, I mean the two connectors are full oiled. Is this the reason of making my car lagging and no power since these two sensors are responsible for electric signals distribution by the control box? If they have to be well dry how can I clean them /?

I almost forgot that the engine is 271 kompressor mercedes c200, and my problem is loosing power, lagging acceleration and no fast response from the engine
thank you bunch

Hi Kais, did you managed to solve your reported issues?

I got a similar car to yours and my check engine light is switched on

I quickly connected a OBD2 reader to my car and it gave me a single DTC code - P0101 "Mass or Volume Air Flow A Circuit Range / Performance"

Is this something to your issue? Perhaps my issue is with the MAF sensor? FYI I changed the O2 sensor but the check engine light still comes on. Is MAF sensor and O2 sensor two separate things?

Thanks

Tony
