Injector replacement didn't solve my issue, thoughts?

The crow's foot and ladies slipper could be picked up at the Home Depot. Do you have 3/4 ratchet to bar the engine over? If so I'd say you'd be able to make do in a pinch. Don't know if you gonna pull both rockers or not. It can be done on an 870 without. I assume the 871 is the same. The real question is which one is bad? I don't recall seeing if you said you knew which was bad.
