When i do a 3rd gear pull full pedal to the floor i start at like 2500rpm and when the car starts accelerating some times its fine i could do a full pull to redline but sometimes i dont know if this would be considerd hesitaion but when the rpms start climbing if feels like the whole car stats to shake in a way the rpm start going up and down as if im about to do launch control or something this doesnt set any codes no cel flash i really am kinda stumped on this

don't floor it below 3k...I don't think this was a problem with the older fuel systems but on the GR and up theres a fuel stumble ~2800-3k rpms...also what is your plug gap/last time you did plugs
