Terrible Hesitation
 

So, my MSP is exhibiting all the classic signs of needing a factory service update reflash; massive fueling, bobbling during mild acceleration, dropping time, the works. I took it to my Mazda dealer and they checked to see if it had the reflash done and they told me it had, but is it possible that they just check VIN's and don't plug into OBDII? Or am I just chasing some other mechanical issue?

I would check spark plugs and make sure they're gapped correctly. I wud check coil packs, wastegate actuator, and maf sensor

hello i in this problem....i change spark and same results
