Well for the injectors I would swap them for two on the driver side bank like 3 and 7. to see if it's the injector.
And for the misfire on cylinder 8, it could also be an injector so you could swap it around also. But sadly when I had a misfire on 8 it was a cracked head for me. I ended up with two junk yard head and had them redone at the machine shop. If I ever had to do this again I would get a new set of heads from Clearwater.

#8 misfire can also be caused by a clogged cat or misrouted wires. You've been dumping money left and right because you aren't diagnosing the problem. Replacing parts in a haphazard fashion is no means to correct a deficiency.
You can have my Oxford comma when you pry it from my cold, dead, and lifeless hands.

I believe there another #8 misfire thread from last week floating around...why is it know one understands how the search function works?...I think I have read here (more than once) that #8 misfire is commonly caused by a plugged cat which is commonly caused by the blown plenum gasket which is commonly caused by (take your pick) the plenum manifold bolts being two long and not properly sandwiching the gasket or the steel plate haveing such a drastically different expansion and contraction rate than the alloy manifold..bottom line is these are all common weaknesses in the design of these trucks and their are thousands of threads already here answering these questions over and over again..its always wise to you search function first then ask questions when you know the answer isnt all over the forum...Just an FYI for the future on how a forum works, not insulting anyone here...
