Hi there so I have a 02 subaru impreza wrx and it's throwing misfire codes on 2 of the cylinders so I replaced the plugs and coil packs and it's still running rough and misfiring at 4 1/2 grand any suggestions thanks in advance.

There is a misfire sticky floating around you can check. It gives a lot of possibilities. I'll list a simple few things to check.

Compression and leak down, dirty or bad maf sensor, idle control valve, vacuum leaks, bad plugs, bad coils.

Besides the plugs and coils have you checked anything?

I replaced the maf coil packs and plugs haven't checked anything else I'll do a compression and leak test on it.
