It has 165000 miles on it, it was sitting for a couple of years before I purchased it. After driving for a month it started making loud noise and stalling. took it to a local mechanic shop and they said engine is gone, has to be replaced. is it possible to trouble shoot all vital parts like transmission, water tank and everything else and restore the car so it will run without giving trouble?

After I took my car to this Benz shop in Mesquite, TX for transmission serving, a few days later when I start the car in the cold months, it shakes vigorously and sometimes I have to start it 3 or 4 times then let it sit for about 15 minutes before I can drive it otherwise it shakes a lot then dies. However, it always easily starts up. Does the AirFlow sensor has anything to do with the temperature? I installed a new Air Flow Sensor and it seems a little better, but it still shakes and I have to still let it idle for a few minutes before driving. In the summer months it starts and run fine. Can anyone help? I dont drive it much in the winter months because it takes too long to idle up. I may just sell it.

my 91 300E seems to run good. I am concerned about the smell of gas . I am due for smog before Mar 8 this year. I am thinking maybe a clogged fuel filter or maybe a new one? I am not to keen when it comes to anything under the hood. I am female and just turned sixty so I could sure use a little help. Thee only other problem I had with this car is the small black rubber square that holds the muffler in place was broken and had to be replaced . I do go for reg oil changes on scheduled dates. So .. any advise on the fuel smell problem
