Well the main thing was vibration when idlling and taking off at lower speeds. To the point it seemed like something really wrong with the car/motor but now it really has smoothed out alot. One other thing I did but didn't mention in the original post was I loosed the injectors one at a time till air started squirting out at the 17mm nut then tightened back. This may have helped out more than I realize. I just did this because I have read where this can help out and I thought I would give it a try. I got the parts from a local MB guy for $21.00 each.
