There was a cracked vacuum hose, mechanic found it and replaced it. CEL gone and the car shifts nicely again.

Thanks

Do need to clean my EGR though, gets jerky and that was one of the codes showing up. Comes on intermittently (the CEL).

Want to put a tank in the trunk for WVO/SVO in the E300 Need to find a place to store my OIL!
Still procrastinating about the biodiesel/WVO
Made some biodiesel but so afraid to pour it all in - I've added some and think I'll supplement my fuel to see how I make out

Made some biodiesel but the process scares me - methanol fumes are not your friend! Need to do this outside.
