Car stumble crusing on low load low rpm

My car is driving excellent for WOT and crusing and it idle well too. However, on low gear, low load and low rpm, it sort of stumble around the 1.5-2.2k rpm mark.
Have any of you got similar experience? Where should I be looking at for a start? I have a NA1.6 and attached my ecu map in this posting.

I'll admit, I clicked on this thread just to see if it had anything to do with eBay.

I've heard it has to do with a badly tuned transient predicted map. Could also be throttle off and on rpm settings. If you search it has been a common issue. I had it too but changed something trying to fix something else and fixed it.
