adjusting idle speed

[henrytad]

hey everyone, couldnt really find any info on this based on a VZ so i thought id shoot it up here.. how do i go about changing the idle speed on my VZ executive? cant do the old trick with the screw as its an electronic throttle. so is it a job i can do or do i have to take it somewhere?

I don't think you can adjust it.
Is it idling too high/low? Because if it is, AFAIK the idle is controlled by ECU, so something else must be causing it.
I shall stand corrected if I'm wrong, though.

Whats the issue exactly?

[henrytad]

its off n on to be honest. in the mornings it idles hard for about 5 minutes, then sometimes while im driving it almost turns off

Could be a shitload of carbon in the throttle body causing the throttle plate to stick but generally that would throw an engine light.

[henrytad]

i doubt it, cause i did a throttle clean last weekend.. do the throttle plates have a life span or anything? my car just passed 180,000

maybe the injectors need sonic cleanning.maybe your maf.maybe even you didnt clean the throttle body as clean as it should be
