2g Idle hiccup log, smog

[gho5tone]

So I've been trying to solve this problem on my for awhile but I'm in my wits end on what is going on with my 6 bolt swap 2g car.

Currently I'm using v2 dsmlink to log and what I've been trying to solve is this strange hiccup. For whatever reason, it is causing me to fail my smog at idle.

So far I've change the spark plug wires, plugs, power transistor, fix many vacuum leaks, and tried tuning it. Only left on my to do list is change out the CAS to a newer one, try a different coil pack, and wire harness checkup.

I was wondering what is the cause of this hiccup. Is it possible to tune it out at idle. Or is this something else.

I've attach a log of my idle.

check coil wires and throttle body for carbon build up,
my 2g nt did this I replaced coolant temp sensor and pigtail.
are you showing a code?

Not showing codes.

I just tried replacing my coil pack. No change. I'm starting to think its a fueling issue.

Update: Did more fixes, fixed CAS, changed fuel filter, and check harness. Now its down to what my idle log says.

Can anyone look at my idle log and point to me the right direction?


Update two:

Don't know what exactly solved this but if I were to take a guess, its a intermittent CAS issue, replacing it with a new one apparently made it better.
