It's exactly that, more a pulsing of revs rather than accelerating and decelerating - tbh it doesn't do it a great deal, but I'm sure it is.

Rev counter doesn't move.

Cheers :thumbs:

Seems nobody wants to help you.

Lambda would cause a low MPG, but the pulsing of revs (I presume), is a hard one.

If you watch the rev gauge does it move at all?

Yeah, great, thanks for your input.

That's right, potentially got a problem with by Fiat already :lol:

When sitting at a constant speed, say 70mpgh in 6th, the car feels like it's accelerating and decelerating on its own. It's ever so slightly though. Initially I thought it was because it's fly-by-wire and therefore more sensitive than the Corsa throttle, but I'm certain this is not the case now and something is wrong.

Also, it seems to use more fuel than I thought it would and I'm not driving that hard - someone mentioned lambda sensor - would this cause an increase in fuel?

Main problem is the accelerating and decelerating though. Any help, advice etc would be great.
