Need help-Poor idling after high rev

[speed2horizon]

Thanks for your advice bro!
But the problem still occur even after I changed the throttle body with a recond one...
I have replaced the idle control gear b4 this, because the idling is unstable (going up n down)...
Now the idling is stable but it is very low (500 - 600rpm) when the aircond is on and gear in D position (mine is auto)... Sometimes engine stall completely...

Ohh.. try open the valve more... let more air go in... see can or not. Otherwise, u can also try the FICD geh...

U mean the screw that control the idling?
I have adjust it to 1000rpm when aircond is off but it still drop to 500 - 600rpm everytime the aircond is turned on...
That's why I would like to try the FICD... Do u think it can solve my problem?

Thumbs up for speed2horizon.. good info that alot ppl didn't bother looking at for quite some time...

I experience the same thing but it didn't bother me.
After high rev, when I stop at the traffic lights, I notice my car's rpm will go down, but i like it because its the perfect rpm! save petrol also. :p

Because my problem is when I switch on the aircond my rpm goes up to above 1k lol!
