Scottish Elises

I seem to only have daft questions to ask on here but I have to ask somewhere!

Just noticed while driving around today in my S2 that whenever i dip the clutch the revs drop to about 1500, stick for a second or two then eventually drop down to a normal tick over.

Any suggestions? Or is this something I've just not noticed before - I don't think even I could have been that unobservant tho...

cheers.

Is the car still moving at the time?

IACV possibly. Seem to get a bit clogged up and need taken out cleaned and poped back in. From memory its only like 2 or 4 torx take it out spray brake cleaner then turn your key 2 clicks so electrics are on but car not starting and hold the top so it doesnt pop right off but moves up a bit spray spray good shake out and see if that solves the problem

Its that bit there

What car do you have , Toyota or K series ? On the k series cars the idle is higher when on the move , think about 1200 rpm . Don't know if the Toyota engined cars have the same feature at a different rpm.

Yotas have the same feature.

I was going to look clever there and you both have spoiled it!

Pic you showed is an S1 - the IACV and plenum on the S2 is totally different mate

Depends on which S2 you have, the location on an early K is the same although the shape is slightly different, but with a clear and concise photo like that you wouldn't go far wrong.

Skim reading But still may solve the problem Suppose it does depend what engine he has but sure someone can point him in the right direction of the IACV

Thanks very much for the replies...

It's a toyota engine, '57 plate, S2. It's still under warranty...I'm not the most technically minded (the picture and description were a big help so thanks s29ttc- I might just take it back and see what they say - I just didn't want to be taking it back for no real reason.

Question - is it still moving, then dropping idle as you come to a halt?

If so - don't take it back, they all do that. It's part of the mapping. Nothing to do with an idle valve.

makes no odds - on stop or coasting same issue..

maybe it's just me picking up on it now - the more i drive the more annoying it is because i know what the engine tone's going to do!
