Yeah I think my Haynes manual says it should idle at about 850 or something?

Do you guys think if I took it into Vauxhall they could reset the idle on their Tech 2 or whatever?

(sorry for hijacking your thread Mr G.)

my nissan turb idle'd at 550

550 is too low sam

The cat on my (mk3) Astra is stuffed, my idle is at about 550rpm, sometime before February next year (MOT time) I'm gonna get it changed for a new one, and see if I get the same problem still or not.

Idles at about 1000rpm when cold, and slowly drops down to 550rpm when at normal operating temperature, weird.

I don't know that it is, thats the only thing I can really put this idle down to. No EM lights or clues there. There's just an increased bit of noise towards the back of the car, sounds a bit like front of the back box, near the axle. Need to get under it I suppose.

Car is nearly 3 now like, 35k.

the zaust on the coupes (and mk4 astras) is twin skinned so should be lasting at least half the cars life...

where is it blowing?

although the second lambda probe only checks the operation of the cat

What car is this on? the astra coupe in your avatar? if so it could be possible, as chance's are it'll have at least two lambda's which could be throwing the idle mixture about, thus affecting the idle.

hmm.. it could affect the back presure if its a bad leak... which with all the silly sensors on new cars ... one of them is bound not to be happy causing the fault...

if it were me my first course of action would be to get the zorst pluged up and see if that helps:)

Would a blowing exhaust cause the car to tick over really lumpy. Can feel it through the seat, very annoying! The Astra btw.
