Possibly the vaccum pipe. Check for splits and or leaks.   Does the second air pump work when started from cold?

there is a high pitch noise that go's away within a min or 2 from cold start i would assume thats it, didnt make noise like that till forge valve and went on, i changed the crank case breather for a sillicon one while i was there as it was rotton. how can you tell if it works or not ?

rip it out, there are loads of threads on here how to do it.

hi there, what dose it do ?? and i take it its not needed as you say take it out..

[VRS Mike]

for the first two miutes of start up it blows warm air onto the cat to lower emissions. It's not required in the UK so rip it out if it's causing issues

just been thinking about these

does the variable valve at startup not link in with this system to cause a small amount of combustion on the cat to warm it faster?

if so are there any issues with removal - not sure if folks have thought about this or if I am misunderstanding

vrs mike can you link me up to a removal thread i can not find on, cheers.
