S160 Misfire under acceleration

[neilr]

Guys, a friend of mine has a 2000 Sport160, he's just had it back from a service but has developed a misfire under acceleration, apparently doesn't matter whether this is hard or fairly relaxed acceration. All plugs are new, all plug leads are fixed properly etc.

Is there anything else worth checking? If it goes back to the garage he won't be able to use it for Le Mans!

At a rough guess this sort of this is often ignition component related, but I'm not particularly familiar with the K-series....

Try the fuel sender, mine is a 2000 car and its on its way out.

Had that exact problem two weeks ago and spent a lot of money with Lotus doing tests on it. It turned out to be the spark plug leads! Costing £20 to replace. if you have not replaced these, do so and I am willing to bet this will fix the problem. This problem happened on my 2001 Elise
