Hesitation around 2,000 rpm

[Ross75]

Went for my first proper drive in my new Tuscan this morning. All running nicely, except:-

There is a definite hesitation around 2000 rpm, feels kind of lumpy. After it had warmed up properly I noticed it started at 1800rpm and went away after about 2500 rpm - only noticed on light throttle, although that's just because I don't floor it at such low revs. I don't think I've gone over 5k rpm yet, but haven't noticed it happening anywhere higher up the rev range.

Going to have it serviced soon anyway but thought someone might have heard of this happening before. Only thing I've found from the search is maybe new HT leads - any other ideas?

Thanks.

I had this problem with mine...I ended up having a new Lambda sensor and the throttle bodies sorting...

Thanks for the reply. I had the combination of "2000 rpm" and "Lambda sensor" in my head but not sure where from. I think it may have been from my Impreza days.

If its happening whilst cruising (rather than accelerating) then its often the throttle bodies that are worn. This is a common fault on SP6.

There is a better after market component made by 'dreadnought'

Thanks Tusca, it is definitely when on light throttle that I notice it.
