Past problem was CEl would flash, idle would have the shakes, and dealer would replace either CP 1 or 2. Now it appears to be the opposite: past 100+ mph, the CEL flashes and it goes into withdrawal.

Also noteworthy is during the entire drive, the car feels "heavy." Any suggestions? Could it be the plugs?

Borrow one, and let us know what the codes actually are.

which btw is in German so once I get the printout I'll run a translator on it and post.
However, was wondering if anyone else experienced this symptom(s).

at least post the codes
