Would a bad MAF only show signs with load?

So, I'm pretty sure we've got a MAF issue this time.

I checked voltages on the white wire of the MAF, 1.7 at idle, 2.6-2.8 at 4000RPM. Obviously not right, right?

So there are not issue while the car is in Park, but once on the road, I definitely have issues with sputtering and hesitation when I apply more than slight pressure on the gas pedal.

Cap, Rotor, Plus, Plug wires were all replaced when trying to troubleshoot this.

It was running like crap at idle, unplugged the MAF, plugged it back in, and there has since been no longer an issue at idle. Only happens when actually driving the car. I also cleaned the MAF with no luck.

Input?

Is your CEL on?? If so, what codes?

Code was for the EVAP Purge Solenoid, since fixed.

Had a friend pull a MAF for me. Welp, said MAF did not work. Read 2.6-2.8v, again.


Went out and bought a brand new MAF, 2.6-2.8v at 4000 RPM.


Engine grounds show continuity, TPS is checking out. I'm so lost. Ideas?
