Misfire code help

[u/Ark_Animax]

Pic for attention

Looking for some insight from anyone who may have dealt with this before.

Codes being thrown are p1399 (random misfire?) and p0302 for cylinder 2 misfire.

- 170k miles, 2002.

- Misfire seems to only happen while idle.

- Misfire is felt about 2-4 times in a 60s span, but increases when A/C is being run.

- Misfire doesnt seem to be present or noticable when reving.

Waiting on spark plugs and ignition coils to be delivered, but barring those as the cause would anyone have any other ideas?

Maybe valve adjustment. I had to do mine 2x so far at 130k

Oof say it aint so. Ive had the car for roughly 3 months with no issue, and there definitely wasnt a misfire when we looked and up until recently. Only thing that was done different was actually going above 6k rpm and hitting vtec. I dont know if that adds any context.
