Been happening for a little while with this, only occasionally in a high gear at lowish speed, sometimes the power is a little 'fluttery' when accelerating gradually. Does this sound like the N75 valve? When accelerating hard the car does not exhibit this and pulls very cleanly without hesitation. Its a 2001/Y with 45k.

I think I get this too....

Also if I lift off sometimes it is as if my right foot isn't sensitive enough as the revs die quicker then I'd expect?

Plus if I brake and leave the car in a high gear if feels like it will stall earlier than I'd expect?

As you say the remap is very clean otherwise....

Hmmm I dont experience that, just the slight fluctuation as the power comes in quite low down. Its not a massive issue but slightly noticable. I need some better tyres for the front as the Conti's are struggling with grip!

I've always thought the octy rs is difficult to drive slowly, it goes great if your giving it a little or a lot of boost. But in low or no boost situations it's not smooth at all i find driving in traffic in built up areas hard work. It maybe a fault somewhere but i can't really see that as under hard driving it goes great

So i just live with it

Hi all, had exactely the same problem until about an hour ago, that was when I took off the throttle body and cleaned it with large amounts of carb cleaner to remove all the black gunge around the throttle butterfly, put back together and just come back from a test drive and happy to say problem sorted.

You need to take the throttle body off so you can get to the reverse side of the butterfly and the very back of the body, be gentle with it when you remove it as there's a paper gasket between the body and the inlet manifold.

hope this helps.

Hmmm interesting, thanks for the tip.

Cleaned mine as above a while back, now runs as good as new. Mine used to hesitate in second or third and only took off when you put foot fully down.It was a pain when changing up as revs seemed to drop off then pickup again.Anyway all fixed now thanks to this forum and their members.

I presume this has come on Liverpool Lad after your remap?

mine did this a touch after being mapped but ahve never found it difficult to drive at low speeds or low boost infact i find it a very easy car indeed to drive around town, even the missus can drive it :eek:

I think so. I can live with it, just wondered what caused it.

Had a similar problem and it was down to a split pipe on the turbo?
