Every now and then, after been sat in traffic I seem to notice more. Once I put my foot down on the clutch to put into neutral. My rev note sounds like its hunting slightly. Then it levels out to normal. There isn't much idle needle movement. It almost sounds like the fuel pick up from the tank sloshes back and forth from stopping.
I bought a Revo PCV delete/blank and noticed it did it more aggressive. So I fitted my PCV again which is just under a year old. Still does it but not so aggressive.
I'm getting it booked in soon for a Terra Clean hoping that would clear it.
Any other ideas where I should be looking?
Nothing picks up on VCDs.
