1ZZ throttle dismantling

[EliseNick]

Hi all,

I've been having problems with my S2 Elise S, very much as described in this thread;

http://www.pistonheads.com/gassing/topic.asp?t=104...

I found a webpage once where someone described taking their throttle apart, replacing the gear lubricant which had plasticised, adjusting stops etc. Unfortunately I can't find this page now, but not to be dissuaded I've taken the throttle body off anyway. But I can't get at the workings of it because it is riveted together. Is there any way of getting into this? Or should I just cut my losses and get a new (or second hand) throttle?

Also, just out of interest, why is it cooled? That was a slightly messy surprise.

Any input appreciated!

Thanks for the update, that sounds like a good avenue to pursue. I'll give it a go.

Just to update this for the sake of completeness - I had mine reflashed, and four months on I've had no reoccurrence of the problem. Thanks for the tip!

...and the problem is now reoccurring.

This is after I had the battery disconnected for a few days. It has clearly lost some settings, because a) the software revision number displayed on a stack reset is now 1.00.00 (or similar), whereas it used to be some later version and b) the arm/disarm alarm beeps have been activated. However, I had the ECU software checked by a dealer, and they told me it was up to date. They also told me the number displayed on the stack isn't relevant. This all happened long enough ago that it would have relearned any settings.

Anyone have any clue what vital information went missing during a couple of days of disconnected battery, or otherwise shed light?
