1200 miles, less than 100 since the 1st service and I’ve got a nasty misfire and lost most of the power! And it had been running so nicely.It’s happening from about 2-4000rpm and there is just no power above that.I’m hoping its just something like a loose lead. Could somebody please direct me to them or provide any other ideas.Ian [image]http://www.exiges.com/ubb/NonCGI/images/icons/frown.gif[/image]

HiHad a very lot of problems like this. Bought mine in December with 5�000 km. Am running now with the fourth ECU (190 hp). There where two new ones from Lotus with missfire � problems!We found two further, real errors. First was a sick vacuum switch for that bloody inlet flap. We disconnected the last two ones. (Are sitting on the left side of the motor under the panels).The other one was a defective crankshaft sensor. Here we are not quit sure, if the sensor was mad or was it a bad contact. You may disconnect / reconnect the cable to test it. (Have to demount the 10 cm high alloy-panel between the motor and the boot to get to it.).We are also not sure (but it seemed to be), if it was helpful to disconnect / reconnect the mainplug between the ECU and the motor. (Bayonet joint located (invisible) at the wall between the driver (LHD!) and the motor.)Mine is OK now since about 1�200 km �HTHThomasPS: Sorry about my English � I am fighting against it�

Thanks chaps but nobody’s given me the quick fix that will solve my problem in 2 minutes yet! Keep the ideas coming.Battman isn’t plugged in during driving. It seems to be doing its job with the new battery. Battman was getting a weekend sidekick on Saturday - Airflow Man. However, it now looks like Exigey will be at the hospital.Ian :neutral_face:

Turned out to be a blown spark plug - good effort Ian!Hopefully the rest will last longer than 1200 miles!Ian [image]http://www.exiges.com/ubb/NonCGI/images/icons/smile.gif[/image]
