Exclamation LS1 Missing Need HELP!!! (video included)

Ok i have done a ton of searches and this is what I have done up to this point.

There is not a check engine light (see video)

Replaced all plugs (NGK) which did help a little
Tested all wires (MSD)
Tested all coils (Stock)
Replaced O2 Sensors
Replaced Tune (Nelson mail order)
Changed Oil (Mobile One)
Changed Fuel Filter

The video will show you my problem. I'm not sure where to go from here.

could be a bad injector or loose injector conection...ensure to check all connectors especially the PCM one. go get some die-elctric grease and lightly coat all connectors in engine compartment.

also check that you don't have a broken valve spring or damaged rocker.

Ok I'm going to send the injectors off to be tested and pull the value covers and inspect the springs.

Dose any one else have any ideas?
