Hi, I have a 88 300ce with 175000 miles on it. I have searched various MB forums and found many things can cause the problems that I am having. The problems that I am having are:

1) when I first start up the car it runs little rough - shakes a little. the rpm stays around 750 but fluctuates a little +/- 30.
2) the car runs smoothly until when it is coming to a stop or at a stop. It then will start to rattle with fluctuation on the rpm 550-800. Sometimes it stalls when reaches below 500 rpm. The car usually starts right up but sometimes it takes several tries.
3) after 20-30 minutes of running the rattle and rpm fluctuation decrease and no stall at all.
4) lastly, when the car is parked the rpm usually stays at 1000 steady until I gas it a little. Then the rpm drops back to a steady 700 or so.

I know that there are many things in the car that can cause the problems. But I would like to know would a faulty/dirty ICV cause all these problems, then decreases in severity after 20-30 minutes of driving?

Thanks

Rick
