What's wrong with my Mercedes?

Major cause of sudden loss of power

Begin with the "back end" fuel delivery system first.

Already done filters, injectors, tuning and still want more power - there is one more thing you could do.

Most owners forget about the fuel injectors - Cap, rotor, wires and plugs may not be enough

Here are some things you should look out for!

Sometimes it can be something quite simple - other times not...

Depends a lot on the climate and how the car was stored but you should always begin with new fuel and filters

Very important for cars over 20 years old.

Some will need to be "back flushed"

This is a very common problem on the 602 and 603 diesel engines

Common fuel leak problem but repair must be approached with care

Fuel Line and Transmission Cooler Line Leak Prevention

More common than you think and easy to fix with right tools
