Thanks for the reply Doc.

So, I should get the air mass checked out first? Do you think this is what's causing my problems? How do you determine if the MAS is dirty and needs replacement? Will any check engine lights come on? Reason is, I dont have any check engine lights on or anything. The car just doesnt have the torque it had when I bought the car. Do you happen to know the part number for the MAS for my 1995 C36?
Also, what are signs of a bad ECU? Would the car even run and would any check engine lights come on? Why do you think they are telling me to replace that?
Sorry for asking so many questions but this is my first Benz!!!
Thanks again for your help
