Hi guys,

I am a new owner of a 2004 montero sport limited 3.5 V6, with 27k miles on it.
Now here is my problem a few days ago i noticed that my RPM is at 1000 when AC is turned on and 1500 when turned off, this should not be the case as i know RPM should be lower when AC is off.

Anotherincident is when i was driving my idle dropped at .5 then .25 and then engine went dead..it starts though right away and i was still able to drive home i turned AC off though just to make it home but the idle seemed stable.

Is this a servo problem?

Any help is greatly appreciated!

Many thanks,
Charlz
