idle at 2000 rpm???

zub · 09-04-2012, 05:45

not sure whats happened, but car is now idling high, sits at around 2000 rpm.

any ideas why? and what i should check?

the Idle control valve might have stuck. take it off ( 3 screws ) and check if it slides smoothly. if not give it a good clean with wd40. worked for me.

cool ill have a look if i can find it, where abouts is it located?

under the throttlebody.

thanks mate. looks like its easy enough to remove.

have read on here to try disconnect the battery for 20 mins as well.

seems strange this happened after saturday. on sat my car broke down, i looked around the engine bay when this had happened and i notice on the hard pipe, there is a small samco hose with a blanking plug in it, but the plug was actually out, so once i re fitted it the car was drivable again, only thing was that it was now revving higher than normal after i re fitted this.

havent had a chance yet to do this.

any one ever had this and then disconnected the battery and every thing ok after?

or need to remove idle controle valve and clean it?

I've tried both. But if the idle control valve is dirty it will not run smooth in and out.
Then the Idle control valve will not reset itself.Take the intake pipe off, unplug the connector and unscrew the 3 bolts holding it and give it a good rinse.

cool is it that easy.

just seems strange that this happened just after it blew out the blanking plug on sat.

Will the sensor not have to be reset if you remove it,

I didn't have to.
Every time you turn the ignition on it gives the ICV a pulse to adjust.
