1jz supra stutters
 

My 1jz supra stutters when i drive it, so i change the fuel pump and filter {walbro} and it still stutters it has new spark plugs.... it stutters more so when the car is warmer and when i really get on the gas.. could it be the injectors or a coil pack?

check your coils to make sure they aren't arcing out the sides :)
