I will guess that the economy circuit has an air leak in the vacuum tubing that is used for it. Bill in

Subject: [diesel_mercedes] Idle rough after turning off AC?
Hi ~
I have a 1998 E300
For some time now after running around in hot weather with the AC on, I will park and out of habit with the AC to economy mode (essentially turning it off). As soon as I do this, the idle goes from perfect to rough.
Any thoughts? Anyone experienced the same?
TIA
K
