here we go again...

my car is idling rough again...

here is the problem this time...


when i turn on the car.... the idle swings from 1500 - 1800...
when i turn on the aircon... idle stabilizes at 1200...
when i engage the gear... its at 800...

d problem is when the car reaches operating temperature...
regardless of whether the aircon is on or off... idle swings from 1200 - 1500

when gear is engaged... no rough idle...

help pls...

thanks!
