Hi Guys,
I'm using a manual trans 4g18 waja.
Recently, i found out there the idling speed of my engine is abt 1.2k rpm when a/c is off, but it drop till 900 rpm when i swtich on a/c.
I've try to tighten the idle screw on the throttle body till fully closed.
But there was no different.
The rpm will goes up when i loosen the idle screw. But the rpm will maintain at 1.2k rpm when the screw is fully tighten.
Hope all sifus can help.
TQ
