All the injectors are getting fuel.

I cracked them all one at a time while the engine was running and they all affected the engine equally.

Something else is amiss.

I will keep driving it to see if it improves any.

It could be my imagination but it seemed like it ran a bit quieter after I cracked the lines with it running so maybe a little air was causing some of the problem.
