Intermittent power issues?
Hey all.
Just wondering if someone can lend a bit of insight into this weird intermittent power issue I'm having with my W211 E55. Once every 2-3 weeks, I'll start the car...completely cold...and notice that it's running weird...idles rougher...poor and choppy accelleration...almost like it's only firing on 6 cylinders and the supercharger isn't engaging. No power at all. If I pull over, cycle the key and restart, it's completely fine and it'll be completely fine for weeks afterwards.
Is this the dreaded I/C pump failure going on? Something else happening?
Thanks guys!
EDIT: Forgot to mention. I drove it around a little bit last time it happened to see if it would throw a code. Nothing...no error/malfunction/CEL's. Very confusing.
