Hi Folks, I have mercedes C180, 1998 model, my problem is, the engine stalls and vibrate violently for about 1 minute when started in the morning or if the car has not been started for say about 3-4hrs. It then runs normal afterward. I have also noticed that the fuel consumption has increased significantly. Any help? thanks

 

check air mass sensor,first before anything...

 

Hi thanks, I would do that then get back to you.
