2002 Mercedes Benz ML320
Engine problem!!!
ok, i have heard stories of this problem from the same model as well....
I got a 2002 benz ML320, and i have owned it since december 2002, i bought it off a ford dealership cause they just so happened to have a really good deal on this. Ok, about 3 months into owning it, every other cold morning or so, the engine will idle really bad, i will be stuck at a red light, and i can floor this baby when it idles bad, and the rpm wont even get above 1500rpm. S i have to turn it off and restart it to get it to run fine.
The next problem that i think has to do with the engine idling rough, every other morning, whether cold or warm, its when i havent driven the SUV within 8 hours, there will be a HIGH PITCH beeping or constant squeel/beep for a good long time, even turning the key over without starting it will do it. One day when it happened, it didnt turn it on, just had the key in turned over, i went down under the dash to see where the sound was coming from, its coming from below the spedometor, behind the brake pedals, sounds like on the firewall or behind the firewall.
I have taken this into the benz/ford dealership (ran and owned by ford..... figures), 7 times.... 7 times they cant figure anything out cuz it doesnt do it for them there, but it does it to us almost every other week. Its still under warranty, it has only 28,000 miles on it. about 6 months after owning it, i bought a Tornada for it, gas mileage went from 18mpg to 21mpg on the freeway....
So i'm hoping some of you hear know of anything about this, cuz i dont feel like having to trade this in, i love this rig. thanks people.

Tornado for an ML 
Those thing for found to be a waste of money, because it really don't do anything.
You should have them check on the CPS or the ICV. Those two failure will not trigger the CEL, thus your dealership will be unable to find the problems.
