Sticking Throttle
Discussion
Just had s1 111s into dealer for MOT and it failed on lamda sensor. Dealer changed sensor and emissions ok and MOT passed. Since picking up car have noticed throttle is sticking at 1500 rpm after accelerating. once throttle is blipped it returns to around 900 - 950 rpm. It was perfect before coming out of the dealers and as you would expect he has denied thay have been anyway near the cable and it is a co-incidence that the cable is sticking (dealers explination). For info car is standard any ideas.
Yeah . . . TADS . . . 
If the throttle body (the bit with the throttle cable attatched on the engine) is black it's the plastic one, and these are notorious for sticking, giving you idle at ~1500rpm and returning to idle after a blip, sound familiar ?
Conincidence I recon, the only thing that can cause them to start to stick is overtightening the jubilee clip on the throttle body, this can deform the plastic moulding and cause the butterfly to jam.
Only real solution that lasts is to replace it with an alloy one, either a standard replacement in alloy or a 160 throttle body, only issue with the 160 version is that you may loose some light throttle control . . .
If it's under warantee insist Lotus change it for an alloy one . . .

Yep, had mine replaced under warranty, but it's a cheap DIY fix if you are even slighty competent apparently (I'm not!).
Someone on the other board had an ally one for sale having done about 2k.
Maybe the recent cold blip has started the problem occuring, the reason for sticking is all down to deformation due to heat apparently so cold weather may be having an effect?

milesforrest said: I had the same problem on my S1, sticking between 1500-2500. I don't know if the 111S is similar but a dealer just tighted the spring in about 30 seconds (free of charge) and the problem never returned.
sorry to gatecrash but i read on the net somewhere ( elises.net? ) that increasing the turns in the spring is a bit of a bodge?
sorry, i don't want to spread fear and confusion, but am sure i read this.
do some searching around cos i think this is well documented and i'm surprised the dealer was 'unaware' as lotus have a fix for this issue.
edited to say: nope - www.elises.co.uk under problems i think.
