MAF - Mass Airflow Sensor.

located in air intake. I think its supposed to measure incoming air temp and tell management system how to mix fuel air ratio. It goes out of spec causing hesitation and your symptoms.

Unplug it and have a drive. If things improve you've found the fault.

Oh - you'll need location of said item! Its in the air intake ducting, standing at front of car top left hand side - remove air cleaner cover to get to it. Search on here and you'll find pics!
