Revs when idling

[Gaz16V]

Hey when idling my revs go slightly up and down, (just over and just under 1 thousand revs) what could this be and is it something to worry about?

Either your icv or coolant temp sensor seems to be the common faults

same as mine but seem to of gone away now :P

same happened on my vtr i just ingored it and occasionally redlined it...

it stopped after i bounced off the limiter... for some reason ha
