Buzz test ok, but finding 1 and 4 low to high open circuit. what next?

I am having trouble finding what this means. The buzz test came back as all good. But the scanner shows 1 and 4 as a low to high open circuit. Also when I do a ohms test on the covers all the injectors came in at 3.4 ohms except 5 and 7 Theywere 6.7 and 6.9. So that would make me think that the right uvch could be bad or the injector relays them self on thows two are bad. But I did that before the buzz test. So now I am finding 2 and 4 problems. Leaning towards both uvch are bad . But the kicker is I just pulled both covers and replaced the drivers side and check the passengers. I have only put about 500 miles on it since so I would say that they shouldn't have come loose. But maybe the right side has bad pins.
I am kinda confused on what is going on here and where to go next any help would be great.

1 remove valve cover and unplug
2 clean the contacts
3 reinstall while also doing the 50 cent mod
4 try running
5 if still running like crap pull back apart and swap around the injectors on the drivers side
6 if problem injectors trigger codes on different cylinders then you have injector solenoid issues. replace or upgrade to stage 1's and tune
