Hi All,

On the way to and from Peterborough yesterday the car had an intermittent miss fire, it did it about 4 times in total only for a few seconds, when it happend as soon as you backed off the gas and on again it went, any ideas?

Sounds like fuel starvation perhaps.?

Could it be you are running a little low on fuel?

I havent got a swirl pot in my tank and experience something similar on lowish fuel levels. Im presuming the cause on mine is that the pump takes a gulp of air every so often and cant meet the demand from the carbs.

Feel a misfire - Back off - fuel sloshes around a bit and gets picked up by the pump + demand is lower - car feels ok again.

Just a thought.

Cheers Geoff, plenty of fuel in the tank during the whole trip, think i'm gonna get it set up on the rollers and see wat they say.

If it was sort of chuntering and not clearing properly when coming off idle under load then worn emulsion tubes are a possibility too.
