I have a 64 plate LWB Custom that has had a few issues with what I can only describe as flat spots and lack of power and hopefully somebody may be able to shed some light?
When on light throttle, through a town etc there is a flat spot/hesitation when you accelerate and it always about the same time as the gear change symbol lights up on the dash, then when you change up it loses power especially under load or going up hill. It is more profound in 3rd and 4th whilst on light throttle.
It has also lost what feels like a fair bit of power at low revs and going up hill and now needs to be changed down in order for it to get going, especially whilst going up hill.
Also the fuel consumption seems to have gone all over the place. I filled up yesterday morning and the trip computer said there was 240 miles in the tank. Ive done 120-140 miles and its now nearly empty with the light on. I was driving consistently down the motorway the other day and the Mpg was going from 99mpg to 25mpg without me adjusting my speed, changing gear or going up/downhill???
Its been into the dealer who couldn't find anything so they completed an 'injector learn' that was ok for about 2 days and then I am now back to square one.... If somebody has had similar, I would like to know how they went about getting it rectified..
Thanks
