I moved your post to its own thread.as it is its own issue aside from the one in the previous thread

It could be a bad injector or lack of power to injector.have you checked this

like he said check for power, if you do you can swap and see if the problem moves

check injector for power and it has power. when i first start up suv it runs smooth. after about 3 minutes it misfires.

Switch injectors with another cylinder. If the issue moves to the other cylinder, get a new injector. If the issue does not move, do a compression test on cylinder #6. You could have a mechanical issue.
