Hi guys, back again for more DYS or helpful info.
I have a 1991 300CE Benz
Lately I have began smelling a strong gas odder coming from the hood.... The car seems to be running fine but this smell of fuel is becoming over welling.. I am unable to find where the smelling is coming from. I have checked fuel lines and all but I just can not locate the problem.
The second issue is that I have began hearing a knocking sound coming from the rear wheels. Only when Stopped at a stop and then I accelerate. The knocking stops once I get to second gear. Also it only seems to make that sound when turning right. Any ideas? I have lifted the car and was unable to find any thing hanging on the under body. Lastly, does any one know if a 300CE (91) have rear brake sensors? I just had my brakes pads and rotter's replaced in the rear and they said my car did not take rear senors even though Benz told me I needed them. Thanks so much for your wisdom and help.
