weak or dead spot in the Air Flow Meter - very likely.
Have seen it a few times...
one van in particular ...slight miss right at 3,100 to 3,300 rpm...
was reluctant to diagnose bad AFM as it was $ 500 for a new one.

Ending up doing a ton of work to that van , so put on a new AFM ...and that
was it.
And.....driving that van, the way the power and gearing was, about 80 % of
the time in normal driving the engine was right at that rpm...
thus wearing one area  in the AFM - where the sweeper arm contacts what it
rubs on.
