I usually take the injectors out at 100K and have them tested and cleaned. I never cared for cleaner in a bottle. To me it feels like sweeping a room in the dark. You are never really sure if it is totally clean. Besides, the shop can find out whether the pop off is correct or not. The stuff in a can will never be able to do that.
