a couple problems 1991 300SE
 

Econ gauge just today I noticed it doesnt work. its reading horrible economy all the time. just stays there. stuck to the right... no idea where it gets the reading from. not sure if i care about what it reads either. but something else could be wrong to make it do that. Any knowledge that may be bestowed...

Im pretty sure its what i think its is but slow clicking from the front when i make a left or right turn is...

passenger side engine mount was flat and i dont know what the driver side mount looked like. So I replaced both to be safe. new passenger mount is almost flat again within same week I put it on...

check the vacuum check valves in front of the fusebox you will find a loose conection for a least one vac line two options 1 replace valve 2 cut back silicon line and push back on to valve tightly.

found a vacuum hose that was loose. works now. thx

Isn't it great when it's easy....?
