Default Bucking at low rpms and load (stock)

Well as the title says. I have cleaned the maf, and it didnt really help. I think i have some bad check valves in the AIR system... could this cause the bucking. Its usually right at 1500 rpm if i hold it steady. On or off the gas and it will stop.

So does this mean that something is throwing off my AFR? Then that would mean that it would not be something like bad motor mounts correct?

Does anyone know? The o2 sensors are the biggest thing when determining AFR. But im not throwing codes. So does this lead me to the air check valves? No one has had this problem?
