Well, after poking at the car for a while, I decided to adjust the idle up to see if things would smooth out. HUGE MISTAKE! The worst thing I could have done was mess with what is apparently a factory setting not to be played with. All I can say is that I love the guy who invented the 5 degree indexing ratchet wrench. Not an easy little nut to get to and almost no room to do anything with.
After getting the idle back to where it was, I discovered that the molded hoses for the ICV has cracks on both of them. With out a store with an inventory of near 20 year old benz parts on hand, I opted for digging through my electrical supplies and pulling out the cable splicing tape to wrap the hose with.
The car ran better at idle not ramping up and down as much and held at just over 500 rpm while at stops in drive. With out knowing what it is supposed to idle at in that situation, I'm just happy it's not stalling out now.
