Since I got my pathy a few weeks ago, i have had a rough idle-most noticeable when just warming up the engine. I also noticed today that if I turn on the air conditioner when this happens the rough idel seems to go away. Q- how does the ac affect the idle and any ideas as to what this problem is??
(already replaced plugs, air filter, fuel filter, pcv vlave) thanks guys

ps- the rough idle is best described as jumpy- it revs at a given rpm and then it will drop to a lower rpm for a second and then return to a higher rpm

Also, I ran the ECU diagnostic and found nothing. Anyone with ideas?

The ECU compensates for the additional load of the AC compressor through the Air Induction Valve.
When the engine is cold the Air Regulator is opens a bypass to raise the idle.
Your problem may be in the Air Regulator.
