Mass Air Flow sensor, if you already done the diagnosis with al nael computer and not shown any abnormal result; mean it is okay. That sensor is normally not a major issue.
Damaged MAF sensor just easily can be detected in 'check engine' warning light at your meter panel.
Try to change the spark plug too.. It is only qr14. My rexton is using Bosch Super 4. It really improved. I bought those during my outstation in Berlin last year.
Check also your spark plug cables from any leak sparking. Replace it if necessary. One of my rx320 friend here faced that problem before.
