300e Stuck Accelerator HELP

[immunity]

Was headed down fdr highway in NYC and my accelerator got stuck!!! After a harrowing few near misses I was able to pull off the highway and slam the brakes and cut the engine. After that every time I started the car(neutral) the rpm kept goign up and up. I pumped the accelerator...tried to pull up the kickdown switch...its pops up and down but still the revs keep going up. I did some searches on the forum but need some precise advise as to what to do exactly. Any help would be greatly appreciated. To think I just spent 2K putting a new engine in. The car is on the street and I have go do something right away.


p,s How can Mercedes have a fault like this...its a disaster waiting to happen...that almost did.
