RPM dip at idle on '05 CS
I have a phenomenon that occurs under all conditions but is worse when cold on my 2005 CS.
When coming to a stop at a speed faster than a crawl, the engine RPMs dip to 400 rpm on the tach and then recovers back to normal speed of about 500.
I can hear the engine lug down a bit when it hits 400 but quickly recovers.
This issue occurred a few years ago but was "fixed" at the dealer by cleaning the throttle plate.
Before digging into the intake, I wanted to see if there was a definitive fix to this issue.
Anybody else seen this?
