[QUOTE="cb70, post: 1303120, member: 14467"] Guys, I've read this article (similar to my case) somewhere & lets discuss it together, ".[FONT="Times New Roman"]..Since the engine idles well with the air-con on, we can assume that the idle bypass valve is working & feeding enough fuel to keep the engine revs up. However, since the engine has difficulty in idling withour the air-con, one of the place to look at is the[B] throttle position switch [/B]on the side of the throttle butterfly. With the engine off & the throttle fully closed, [B]move the throttle slightly open[/B]; you should hear a "click" when the switch activates. If there is no click, that would mean there is insufficient fuel for idling [B]and the switch will need to be adjusted to activate[/B]. If you get that adjusted correctly and still the engine is not idling properly, you may have to adjust the [B]mixture screw on the air flow meter[/B] as it may have closed in too much due to wrong adjustment of the throttle switch. These are the two likely sources of the idling problem...[/FONT]" [COLOR="Blue"]What is "throttle position switch"? Where is it located basically? Is it similar throttle screw? What does it "meant by move the throttle slightly open"? What is "mixture screw on the air flow meter"? Where is it located basically? What does it meant by "and the switch will need to be adjusted to activate"?[/COLOR] Thank guys. [/QUOTE]
