Weird engine stall 2006 - 195,187 ODM
 

My 06 Tuscan has been great, I've had it since it was brand.

I'm at 195187 miles. It just started acting up intermittently.

It will lose power momentarily and then continue as normal. It varies sometimes 1, 3, seconds. But only a couple times a day.

It's acted up on climbing this particular hill on two different days for at least 2 minutes. I pulled over in the exact same spot both days.

This is what it sounds like.


It will stall occasionally while doing this. When I pump the gas it stumbles better but never gets faster. After a couple minutes it will just change back to normal. It's only lasted long on the hill.

I know it's not the transmission.
There is a mass flow sensor code.

Any suggestions?
Anyone else have this similar problem?

Thanks

The knocking noise in the video is me unlatching my hood

I didn't watch the video. Maybe the TPS is starting to go?? I've seen it before. Years ago when I worked as an Auto Tech. Its a Variable Resistor. Maybe its getting some "Dead Spots"
