hello to fellow 'jetters,

i have noticed with my trajet that sometimes when the aircondition is on, i noticed that the way the engine idles specially if i am stuck on traffic, it's a bit rough (not rough to the point the engine is struggling but the seats are shaking), when i turn off the airconditioning system, it idles smooth, there is no sign of loss of power specially during take-off, just noticed the rough idling. does anyone know how to adjust the idling to a V6 2.7 ltr.? thanking you all in advance....

I don't think there's anyway to adjust the idling. Every thing is control by the ECU.
As for your problem, have you tried changing the Spark plug or check the cables?
:)

the above post is right, you can not adjust the idle speed. are you sure the air con. compressor is not loose on it's mountings and causing it to vibrate?

i did changed the spark plugs last year, i used the recomended plugs for this model which they told me should last for at least around 60,000 to 90,000 km.
as for the leads, maybe i should try changing it too. tell me, if there is something wrong with the plugs or the leads, the car should at least be shaky and i could hear the engine sound like it's coughing or choking. but it's not, and upon take off from a full stop, i have no problem,it accelarates smoothly as if nothing's wrong. but i'll still do your avised and that of montego, thanks a million guys.....i'll keep you posted...... :460:

or probably i'm just too paranoid about that thing i feel about the car. but never the less, i'll check those things you suggested to check. the last time i replaced the leads was back two years ago (i think), is there any time span that the leads should be replaced? i know that the plugs that i used in this model is to be replaced every 60,000 to 90,000 kms. the same time that the rear plugs have to be replaced (V6 2.7 ltr). i forgot the term they call those spark plugs, (they are the pointed type ones), something sound like irridium plugs? (i'll check my service book). again, thanks for your help......cheers..... :beer:
