P0300 random misfire.

[Eg.h2o]

Could be the plug wires, the coil, or oil in the spark plug tubes depending on the year.

it's a 2006 I checked plugs and tubes, haven't tested the coil yet. I had an aftermarket pod filter on the car, which I reverted to standard. idles better with original airbox, but issue still persists.

To add to this, just did an IACV, and now idle is consistently at 2500-3000 rpm when I go off of the throttle.
