Have a 2013 Chevy equinox 2.4 flex fuel. 184k miles on it
List of parts that have been replaces
MAss flow,high pressure fuel, fuel pump, O2 sensor. New spark plugs.

At random when going down the road. You go to accelerate the engine is having trouble accelerating. It doesn't feel like a miss fire. It feels like lose of fuel. So I replaced the fuel pump in tank. (High pressure was replaced last year) thinking that would fix the issue. Nope it didnt. I'm still having the same problem. It will loose power you stay in the pedal then out of no where it will jerk and power will come back. Engine will run fine for a bit then do the same thing again. I have no codes at all. She idles fine. No misfires.

I'm at loss right now. I thought it could be the vvt actuators, could be lossing timing?

Anybody have a suggestion of what else to check. Again no codes.

If you've only scanned generic OBDII codes there's a chance a comprehensive module scan might turn up something.
