RRGrassi. Thanks for the info.

I will check to see if the engine shutoff vacuum line is connected.

Once question, where is this line?

Also, do you work on these cars?

I am new to having a MB car, so pardon my little knowledge, but what chassis models is this car 116, 123, 126 or 201?

Thanks for all your help. I guess one of the benefits of owning a MB is the networking help other owners give you
