Fluctuating revs when pulling up to a junction.

[Pete H]

Ok lads, sorry it's just a quickie, my turbo has been sat on my drive for a few months, starting driving her yesterday.

Anyhoo when i pull up to a junction/traffic lights, and dip the clutch the revs fluctuate about four times then sort themselves out and it idles normal, when it fluctuates it's below 1000rpm by the way.

Thinking clean idle valve, do they have one, or could it need a throttle body clean out?

you could have a air leak

i had something similar on mine but was over revving for few seconds. Did a Throttle body clean and it sorted it. Worth doing for the cost of some carb cleaner.

i thought that, but then it'd be doing it all the time id imagine.

probably my next option, sure there was a how too on here but i cant get the search engine to work.

Mine was similar, it would idle between 600-900rpm for a couple of ticks before leveling out at about 900rpm

Cleaned the throttle body at the weekend and it sits perfectly at just under 1000rpm now

Was very simple to do....is a good guide !
