Engine problem ( video inside )

get a noid tester or if you have a test light, test the 2 wires thats going into the fuel injector. one wire will show constant power, the othe one will show a pulse. You can compare to the other ones.

If ur spark plug came out perfectly fine does it look the same as the other ones in the other cylinders? if not then something is going on there.

have you did the other thing i said, hold the spark plug wire connector near a ground to see if you have a spark?

Yes i have a spark. And i took the spark plug from another cylinder and switched it with the " bad " cylinders

No diffrence at all.

Today i pulled into school and my car had the infamous idle issue. It reved up to 1500rpm then dropped off repetitively. I came back later today and the issue was gone

Ill check everything over when i remove my intake manifold to do the h23 swap.

see if you can get a test light and test the wire going into the injector.

I think you should try to fix the issue before you do ur intake manifold swap so that if you need to change or add a part you can do it while in the swap.

as for the idle, usually the idle is adjusted to high or incorrectly. Or the fast idle valve is improperly adjusted.
