Are we sure we are not thinking idle adjustment/idle control valve?? Just a thought

Isn't there a procedure for checking/setting the idle?

yeah there is but i am not sure its the idle on its own it idles fine until he switches it off then restarts it

Ah shizz, me not reading it properly

you see I thought of idle control but it would be at worst when cold no? or is fast idle forcing it open to allow pre heat and so im only seeing idle control valve proper use once its heated up and switched off then on? would that account for raggy low end revs between gears?

why do you switch it off? does it idle ok if you just run it up from cold?

yes but take offs and low end revs are still pretty rough even when engine is fully warmed, by switching it off I mean I go a run come back 5 mins later fire her up again and cos she is heated revs just sit around to what looks like 400 to 500.

so you can imagine I look and sound like im just learning to drive high revving out of every junction to prevent stall haha its brutal like.

So, you start from cold, let it warm up and when it's up to running temp it idles fine? Then you switch it off, restart it, and then it will sit at a low idle and "judder" when pulling away??

yes in a nutshell but still judders if I drive off from initial start up too.
