Hi a very good friend has just baught a beautiful M100 Elan. He is a bit of a "project" car buyer, so I was pleasently surprised when I saw what good condition the car was in.
There is one problem, under 3000 revs the car wont idle, it hunts and stalls.
The previous owner has tried everything. The head has been skimed, new turbo, new crank sensor, new coil and even a new loom.
Any ideas what the problem could be and suggestions on how to solve?
TIA

Take the car to a specialist who knows what they're doing and can diagnose the fault and then simply fix it.

It may be something like the oxygen sensor
My Esprit did a similar thing when it failed.
If you can get the damn thing off its worth replacing at 60,000 miles anyway.
How many has it done??

It has done about 79000 but it is a j reg and has no cat and therefore no lambda sensor. My main theory is some sort of leak in the inlet manifold or intake fault. Any ideas?
Have you asked the same question on www.lotuselancentral.com? It is a site devoted to the Elan M100 and as such you're more likely to find people knowledgable on this car there.
Not saying that us PHers can't help you, but you're more likely to find someone with experience of this problem there.

Check out Elanscan on this site http://members.lycos.co.uk/mcnica01/D It's an interface cable and free software to let you tap into all the engine sensors and diagnostic functions using a laptop PC.
There are several sensors on the engine that cause trouble like this when faulty, EG a false coolant temperature reading of minus60°C leads to massive over-fuelling at idle, etc etc. Elanscan lets you monitor all of these readings in real time and log the results.
It's also fun for measuring 0-60 times

Hello
Fellow M100 Elan owner here!
LEC is the best place for all queries, parts and knowledge. Plenty of get-togethers also.
Donington on 18-19 March is an excellent meet up and Lotus show. We hope to rally up more than the 80 plus cars we convoyed for this years Donington event. Hope you can join in!
Not too familiar with your problem myself but I'm sure one of the meny members on LEC can help you.
It's a fantastic car (slightly bias opinion of course) so I hope she gets running full speed soon!
All the best!
