Check Engine Light

I recently had my check engine light come on and would like to locate the issue and get it back off.

What I've done so far is that I've taken it to AutoZone to read the codes. They told me that the codes are saying misfire on cylinders 1-6. I tried to do a little research on what would cause this and almost all of the info I've found so far points to the DISA valve.

I've removed mine and do not see any issues at all with it. It's not broken and is functioning fine with no play in it. I cleaned it anyhow and put it back but the light is still on.

What else might cause a misfire on all 6 cylinders? The car idles a little rough but not bad at all. I do notice that it is slightly a little more rough than before the light came on.
