Rpm adjusting
Auto, 5th gen, h22a4.
My rpms are adjusting at low rpms around 2-4k. When I rev it up they drop to around 1k, and bounce back up to 1.5k, or so when I let off. It seems to only happen under 40 mph.

I've checked for vacuum leaks, and couldn't find any. I've also cleaned out the iacv screen.
What would be some known causes?
Mod list:
Wrapped CAI, Hytech rep header, Megan exhaust, underdrive pulley, ported stock intake manifold, iab delete, fitv delete, egr delete, evap delete, hondata gasket, water wetter, 1 step colder plugs.
