Thank you for all the information. I don't see how you made it worse unless the injectors were not installed correctly. If you remove them you are suppose to replace the o-ring on each of them and oil them (the o-rings) before installing them. I would check the air filter and the CAT (for excessive back pressure. Also check the rest of the exhaust for damage. If a pipe is kinked or flattened it would need repair. Also GM's are known for some issues with there e-vap systems. You may want to check it out. The gas cap, charcoal canister, vacuum lines. Well good luck.

SOURCE: random/multiple cylinder misfire
if you have done the basics of replacing plugs and wires,
what I found on a dodge that was doing the same thing,
I could watch the misfires happening on the scanner but the engine wasn't missing,turned out to be dirt and things floating in the fuel rail and partially plugging the screens on the injectors.
