1999 Clk430 wont go above 25ish PLEASE ADVISE!!
1999 clk430 150,000 well maintained. A few mornings ago when I tried to start my car it started then turned off two different times before it finally stayed on. it did that again later that afternoon when I left class. Then,that evening I was driving and out of nowhere it just felt like the engine switched to a lower gear. I pulled over and put it in park,then took off again.But she wouldn't go above 25 or so. I'm not mechanically inclined, so its hard for me to describe this.Does anybody have an idea of what might be wrong? Approx $$?

Sounds like the car is going into limp mode. You need to visit a dealership to determine the error codes before you know what kind of repair.

Sounds like a bad fuel pump .. it might be pumping less fuel than needed and causing the lack of power

This will also happen if you put lower grade fuel in there. The knock sensor will detect pre-ignition and go into limp mode.
