last night I reread some of the threads and this one in particular seemed most appropriate - It talks about my symptoms exactly and as an added bonus addresses my thoughts about MB repair as well. It was posted by can-do and ctaylor738 that has helped me here, was also active on that one.

The price for the coil is actually around $140 these days, so I will wait with that and the air flow pot for just a bit - I will first look into the cap/rotor/plug wires. Even though they all have around 30000 miles on them (Is this a lot ? a Little ? ) I will check them out. Initially I did not think they would be faulty,because of their relative "newness" but I am reconsidering.

More to come
