Idle speed control valve info please
Hi to all can anyone explain to me how an idle control valve works please.
I have bought an aftermarket one of ekay and i have noticed that the gap between the shutter and the unit itself down one of the holes is non existent but my old one had a 2mm gap in its unconnected state.
Do these valves sort themselves out as i fitted it and it just idled at 1500rpm not fit for purpose just wondered if i did a total reset on ecu that it would tell it where it should be to idle correctly ???
