Good. you might want to just remove and clean again to get EVERYTHING.
It's 2 10mm bolts and unplugging the cables. Really easy, at least on
the dual hamster models.

Change those first. I bet the problem goes away. Mine was like this
too, i changed the wires - ran a LOT better. It just feels like it's
missing or hesitating every now and then, randomly? or, at low RPM, as
the RPM increases, it suddenly 'kicks in'?

No MAF. MAP is on the intake manifold. I'm not sure about the single
hamster motors, but the two hamster ones have it to the left end of the
manifold.
