ive just finished putting an xein the nova. but it tick over fast. about 1800 rpm...

and when i drive it and come to a top the revs dont go down as fast as they should

any ideas?

its a late type (i think) if it makes any difference.

i do have a plug of on the back of the inlet that i cant find were it goes :S

could be a sticking idle control valve, or maybe thats what the plug is for!

had an xe nova ticking over at 3000rpm not long back, cleaned the idle valve out runs like a dream now!

Is the EML light wired and flashing any codes?

Yellow/brown to earth to check codes

if it isnt the idle control valve then look for air leaks

have you got the knock sensor and iac valve the correct way round ??? or if you have a spare plug is the knock sensor connected ??

mine was revving to high aswel mate, make sure the throttle body is closing properly (the throttle cable not adjusted right out) look at the mechanisim on the side of the throttle body make sure its closing fully

What happens when you unplug the cuts two pin, that make it idle higher, you probably have a break in a wire somewhere.
