BMCC wrote:5th Gen manual says 700 rpm +/- 50 rpm. It is always difficult to read the the counter though. Sometimes mine looks like it is 550 rpm other times it looks like it is about 750 rpm. What happens if you give the car a small amount of throttle. Does the RPM settle to a higher rate or does it go all the way to about 0 then bounce back up?
I'll try that tomorrow.....

I'm sure I read somewhere (cant remember where) that the h22a5 had a target idle speed of around 800rpm which was reduced to around 700-750 in the h22a8 later on.

But could something else be causing this as I'm having to alter the way I drive to compensate, ie, rev like a chav, or is it simply a case of speeding it up?

my gen 4 came with a hunt problem between 300 to 1100rpm found it to be the throttle sensor when this was done the warm idle was the same as yours so low had to rev at lights to keep her going. took off and cleaned the egr and the iacv and she now sits on 650rpm all day.

i think you have a common lude problem, most will @ some point suffer from low (bouncing) idle, mine had this a couple of years ago. it just cleared by itself, usual cause is a blocked pipe on some valve somwhere (is it ivac or something like that). mine would do this in trafic, sounded like it was going to stall but never did. im sure others on here will know as it has affected most of us at some point or at least been part of a thread covering this issue

eeerrr not entirly, std car you see. i keep telling you folks about fitting aftermarket so called performance mods, as i say - horse power is an expensive game. i must say though that my lude IS THE most reliable car i have ever owned, and it seems to repair itself on a regular basis :D std car right down to the anoying bleeps (chimes) even has the rear shock knock :D and i found a jap coin down the back seat. :D how jdm can you get

untouched motor :D std exept for a few leaves
