K&N filter.
Yuck.
Get rid of that.
Put the original box and filter on it.
The original box has a temp sensor for ambient air.
That has to be hooked up.

He suggested the exhaust valves were sticking due to carbon buildup or tight valve guides. This doesn't really make sense to me since he was able to get it to pass (I have the CT certificate) and I was able to drive it over 500 miles without a CEL. Any thoughts on this idea?
Hope you figure it out.

Valve job is cleaning the heads and checking the valve guides, rockers, and springs, then seating the valves using an abrasive compound (to make sure they seal)--replacing anything out of wack.
If wikipedia says different it is lying.
If the exhaust valves "stick" they are stuck open, to my understanding, because the valve is not sitting perfectly flush with the head (because it is bent, there is goo in the way, or whatever), which bleeds off a little of your gas explosion and, I suppose, could suck exhaust gas back into the cylinder when the exhaust valve should be closed and the intake (fresh air valve) should be open.
If you remove the heads and pour water in both the intake and exhaust passages, tight heads will not leak the water. Heads with bent or "sticky" valves will leak little droplets or full blown streams. (This is a poor man's--mine--way to check the valves while the heads are off). You can also check the valves' seals by putting each cylinder at TDC (so both valves are closed), then seeing what air pressure they hold and where you hear a hiss (intake or exhaust).
Anyway, that's what I learned on youtube.
