I took my Z from Aberdaron to Aberaeron last Friday, and picked up a misfire on the way back. After a hundred or so miles I finally got back, poor car running like a bag of something not to be mentioned here. I plugged my laptop in to the car and it told me I had a misfire on No. 1 cyl, fuel shut off. Turned out to be a badly fouled plug, the worst I've seen for many a year. Cleaned it, put it back in and things are fine now.
Filled up with petrol today and did the maths, turns out it did 35 MPG with the misfire, normally about 32. So, turn off one cylinder and you use less petrol. Not sure if I'd want to do it all the time, mind.
Perhaps I'm finally burning off the crud in the oil-control rings, sure do hope so.
