Hi guys,

my car broke down on my way to work tonight. Here's what happened. I was driving around 50km/h when I noticed that my gas pedal was very sluggish (Schwergängig, not sure of correct translation).
So I pressed it down with a bit more force. It suddenly gave in and my engine fired up to 6000rpm even when I let my foot of the pedal.
Panic-stricken I came to a halt and turned off the engine.
I then removed the cover of the bowden-cable over the intake and tried to examine it.The bowden cable was very loose and flaccid. Since the cable is held in place inside some kind of plastic-screw, I tried screwing it back in a little, so it would be tightened again.
I started the engine again but it immediatly fired up to max rpm again, so I quickly turned it off. The cable is NOT broken, however. I can press down the pedal and the throttle valve moves.
I then called the Auto-Club and got the car towed to the a workshop nearby.
I read a bit on the internet and learned that this could be caused by a broken or dirty throttle valve. I'll go to the workshop tomorrow morning, right after completing my nightshift at work. Does anyone have an idea what might have caused this?
Hell, this was scary, especially since the engine was completely cold. I hope that the 5 seconds of max rpm didn't damage anything.

As usual: Best regards from Germany.
