Slight "surge" at cruising speed.

Hey guys.
I've noticed that at around 1500-2400RPM, at cruising throttle (around 8%) i get this very slight shudder/surging thruough the car. I'm pretty sure it's something engine/mechanical related as it's RPM dependent. It only happens at light throttle (bordering deceleration). If I accellerate more, or completly decellerate, it doesn't do it. What sort of engine issues cause this slight surge. Too lean a mixture?? Too advanced ign. timing?
Engine is a 2VZFE.
Thanks.

Nah..no rpm change at all..smooth sailing. Just got this surgey feeling....
I've cleaned the TB not too long ago..so yer..dunno if it would be that.
I have aftermarket ECU support, so i'm thinking it may be advanced igintion timing (apparently it creates this problem...)

Mmm..possibly..but i can't hear anything abnormal with the engine. And there is power there...hasn't lost anything...just this surge. Imagine a wheel being slightly out of balance, except the feeling seems to be from the engine/transmission.
