Engine problem

[strum9]

Hello,

My Lotus Elan m100 has been laid up for a few years and although the engine starts easily and runs well it starts to misfire once warm. The engine warning light comes on and the revs peak out at about 4,000rpm. I stress that this only happens when the engine has reached normal temperature. Could it be the cam angle sensor or would this malfunction when the engine is also cold?

Thanks for help
