[986] Idle problem

[HolmaN]

Main problem:

• The idle is pending when pressing the clutch / going into neutral when having the aircondition on. Doesn't matter if standing still or moving. Has happened to me while not having the AC turned on, but only 50-100 RPM tops, towards the 700 RPM drop with the AC turned on.
  

• Note that this ONLY happens when the engine is warm. (I can have the AC on with no problem until the engine hits 80°C.
  

List of things I've done:

• I've claned the throttle body.
  

• I cleaned the air flow sensor.
  

• I cleaned the idle sensor located on the throttlebody.
  

• I tryed replacing the idle sensor located on the throttlebody. (Borrowed from my mates 986)
  

• I tryed replacing the air flow sensor (Borrowed from my mates 986)
  

List of solutions I've concidered:

• The AC compressor. - Contacted a porsche dealer, and an expert told me they never, or atleast barly ever replace the AC compressors on porsches, since it's almost always other fualts.
  

• Battery not taking enought chargeing?
  

• Gererator or compressor wheel running slow?
  

Video of the problem : (I'm really sorry for how the video was recorded. But it was the best way to hold the phone while driving without dropping it.)

It makes sense to remove the poly-rib belt and check each pulley for drag or wobble.

Do the same for the alternator and AC compressor.
