Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hello, my name is Bobby. Thank you for the question. Can you describe to me how the vehicle is idling and if the check engine light is coming on?
Is the check engine light coming on?
Thank you. It sounds like you may have a weak fuel pump or maybe an air flow meter issue. Since the check engine light is on the best thing to do is to have the computer scanned for codes. Most auto parts stores will do this for free. If you have this done and bring me the codes I can tell you better what is going on and what needs to be done to fix it.
