I've swapped MAF's out. Although the one I swapped to have me a bit of a hesitation around 3k, but still had the RPM drop. I'll inspect the voltage and compare to the manual.
I'll check the throttle plates as well. I don't recall the TB's being too dirty. I'll take a look when I inspect the plates. I should also state this drop in RPMs I am noticing is also slight. I will record it and see how much it actually drops and post those number as well.
