Idle problem

[Andyvalver]

:roll:

My car idles fine when its stood still but when i pull up at lights or something and pull the clutch in before it drops to 500rpm and then when i stop it corrects its self. Its a pain when i pull in at work because i have to turn the car in as im stopping and it stalls because the PAS is sapping all the power when i turn.

anyone know which sensor it is and how easy it is to sort?

Cheers :P

[Lunner]

Clean your ISCV, or stepper motor as teh AA refer to it

[BRUN]

its not a stepper motor on a valver

a stepper motor looks like this

the one on the valver is a valve

[Andyvalver]

Cheers. So what does iscv stand for and where is it?

:oops:

[Andyvalver]

Just thouhght about it lol. Is it idle speed control valve?

Where is it?

[BRUN]

yup it is mate, if you look on ur inlet manifold near the throttle body there is a black plastic pipe with a rubber hose on it, follow that and the ISCV is connected to it, the other pipe goes into the back of the airbox

[Andyvalver]

Cheers mate. Wil have a look now 8)

[Andyvalver]

Smack it with a big hammer :D

[BRUN]

lol, you dont clean the connection mate, you take the thing out itself and clean the inside of it with carb cleaner

:)

[Andyvalver]

lol oh right :oops: I was thinking that actually, wondered if it came apart lol. Will have another look tomorrow lol

[BRUN]

it doesnt come apart.......you get it out and spray carb cleaner inside one of the tubes that the rubber hoses connect to

it looks like this, only this is upside down

i want one that shiny!!!! 8)

[VIPERONE]

check iscv plug

[Andyvalver]

8) Will wd-40 do? I dont have any carb cleaner :shock:

[Lunner]

Nope, won't work as well, and carb cleaner is very volatile, wd-40 isn't

im having the same problem but mines a 1.2, should i try the same thing? or is there ect sensors that may need changing

[BRUN]

if its a 1.2 then its likely to be the stepper motor, get it replaced but might be worth trying one off a low mileage one first to make sure

[Riley]

cheers buddy! any ideas on the cost of a stepper motor
