idle When I turn on the a/c say at a stoplight in gear(a4) the idle goes from smooth to rough. The oil pressure gauge goes from just under 40psi to just a little over 22psi and starts to wave. Idle can be fixed with a little foot in the gas and is fine when driving around but it understandingly bugs me. I cleaned the maf and no change so curious if anyone has any insight.

Well the PCM controlls the A/C clutch relay and when the a/c is turned on it is supposed to delay the clutch while the PCM adjusts the idle (up I would assume)-sounds like that is not happening.
Has the battery or PCM been disconnected recently?
