Hi friends,

First off, I am so grateful for the helpful knowledge and advice you contribute to these forums, whether via thread replies, articles, manuals, photos, or diagrams. I understand how valuable your time is and I really appreciate you offering your expertise to fellow Benz owners in need.

So here's the situation:
I've got a '93 300e 2.8 that starts right up every time (even without waiting a few seconds for other components to engage). Then the RPMs drop quickly and the engine stalls. The engine will shake rather vigorously when the RPMs fall to 200 or 100 as it tries to stay alive.

If I try to give it gas, I can keep it going, but barely. The motor speed is not reflected by the position of the accelerator pedal or the attached lever under the hood. For example, if the pedal is depressed rapidly and/or all the way, the RPMs rise slowly or not at all, with sudden bursts every 5 seconds or so. Once the pedal is left alone, the engine stumbles and dies.

This breakdown into limp mode occurred when, out of the blue, the gas pedal stopped working and fell to floor by itself! When it came back up, I pumped it several times, with no effect. I surrendered, slowed to a crawl, and the the engine went to sleep. I was able to "hop" a few more miles to my destination, but now can't drive home (90 miles).

I have searched for many hours, but was not able to find anyone with the same exact problem. If you have any ideas, I could sure use a hand troubleshooting. Though I've done some small repairs, when it comes to the mechanics of the computerized FI engine and the synergy that is required to make my Benz perform properly, I've got so much to learn.

Thank you kindly,
Casey
