From cold my car starts first turn of the key (battery permitting  ) with no need to touch the throttle. However, sometimes when hot I need to feather the throttle to start it, otherwise it's very reluctant to start, once started though its runs OK. Also, sometimes after a long spell on the motorway, it wants to tick over at more like 1000rpm/1200rpm, a quick blip of the throttle will sort it. At Newent this year when Kevin W was playing on the Tech II with the IAC valve it did something similar re the revs/tick over. The valve has been off a couple of times & flushed out with acetone, no crap in there really, no 3-in-1 though  .

Any thoughts? A N Other IAC valve? Another clear out?

It really does need lubricating mate or there is a tendency for it to stick

If a bit of oil doesn't cure it, replace it

[Andy B]

I suppose that's the obvious answer ..... 
I'll take it out next week some time, back in work tomorrow for 5 days 
Thanks

IIRC the idle air valve was doing odd things on actuator test, like the revs increasing while the valve was supposedly being closed. Makes me wonder if it's had it.

i got a new one from vauxhall about 3 years ago for my old car it was a 2ltr cdxi about £120

I'm inclined to agree, hence the thread, but it won't get a new one. A second hand maybe.  I'll see what lub'ing does - if anything.

Did you sort out the idle-problem, Andy?

Not had chance to have a play - work is all or nothing. I've another IACV to try now though &, weather pending should get chance over the week end. I'll let you know.

if you have the ability to check live data, look at the maf as well

Not at home  but I know a Captn who can

Make sure the throttle butterflies are closing properly had the same problem. for some reason the butterflies were out of adjustment even though the had not been tampered with. Slight reajustment now tickover sits rock solid at just over 500 rpm
