Check the MAF ground. I have a similar problem and last time we find out ground signal was spiking. Sometime signal is good, engine running strait. Sometime signal spike and engine have a thought idle or it hesitate. We have to check three things ( we know MAF is good)
1- MAF plug look in pour shape, might have bad contact
2- ground wire, make sure no short circuit
3-ECU might be going bad

You may want to look at that.

Good luck
Chris
