93 Octane

Checking wmi spray Dsnt seem to be injecting as normal

Pretty sure my hpfp is going. Car cuts up at 6k rpm and wont go past 6k then begins misfiring on bank 2 cyl. 4,5,6. Turn the car off and back on and no more misfires, car runs fine afterwards but will not let me WOT past 6k rpm. Going to replace my coilpacks and spark plugs and see if that changes amything.
