Took the lotus elise 111s out for a drive to Matlock, greet drive out until I got home.
Soon as I pulled up the car died on me I turned the key and the car seemed to struggle to start. I had to apply revs to get it to start up. Since then the card idle problems are causing the car did when at traffic lights and not driving which is making the car not really road worthy.
That day driving I did 110 miles and a fair bit of town driving and all was well, this problem occurred instantly on pulling up.
Does anyone have an idea of what it could be, possible common causes?
I've been told it could be a failure in the cat but wouldn't that make the engine management light come as as there's as sensor attached?

Idle air control valves IACV's are prone to sticking.
There is a small piston inside the IAVC which opens and closes depending on throttle position, if this is stuck it would give the symptoms you describe.
Take it out ( 2 bolts and an electrical connector ) clean with lots of carb cleaner while moving the piston in and out, re assemble and keep your fingers crossed !!
It is always worth trying these simple things first.

Thanks for the advice, I called the AA in the end. He looked at the IAVC and he said that there is power coming to it but its not pulsing or moving at all and he thinks that probably where the problem lies.
As it looks to be an easy fit im going to do the job myself but having trouble ordering the part.
- S2 K-Series engined Elises use a Rover EU3 PWM IACV (Rover MDQ100170 Lotus A117E6069S)
Does anyone know if Im ok to order a rover part and fit this? Im just trying to get this problem resolved quickly and if a rover one is available would that be correct to fit it?
Id be lost without this forum lol

Just a update,
New spark plugs,
Hoses all checked,
ECU reset and TPS reset,
Running better but still not right! ARGH
Cat is rattling, think its broken lose inside, going to order one of them...
Other than that unless anyone can shed some light????, its off to Monster Motorsport and my bank account is going to feel pain!

The cat could well be your problem, if there's a piece rattling about it could be restricting the exhaust. Are you only having the problem at idle or is it giving intermittent problems under acceleration too?

A friend said that you may need to adjust the throttle cable or something as I have a induction kit fitted

Had it looked at, guy said the emissions wasn't right and thought it would be the lamba sensor. Picked it up from the garage the car stopped idling badly and sat there perfectly.
It was like that for around a month.
The other night it started again, so tonight i changed the lamba and its still idling poor.
Any other ideas? :?
