I have a 05 645, I don't have a lot if issues but I have one that when I start it up sometimes the rpm goes up and down and almost turns off.

Any ideas?

It could be from a thermostat going bad, or a purge valve problem. This usually happens on cold morning starts, & is not really a problem to worry about. When you start getting a code, you will find the culprit.

Good Luck!
