Are you reading g/s or hertz (hz) or lb/min?

Your fuel trims are fine. the one side is switching back and forth but always negative and pass side is -3.4 which is ok also.

What is the issue still?

truefire04

still having the same issue, with it missing, or stumbling, i changed out the fuel pressure regulator and pcv valve with no change. is there a way to text the pcm to see if its bad, or is that something i will have to take to dealer to test?

Unplug the maf and drive it. See what happens.

did the maf look bad? that was a 2 min video, i checked it while driving around 80mph, and the lowest it got was i think 20. something and the highest was i want to say 45. something, on the gr/se.
