My Skyline Is Sounding Like A Wrx :/

[sama1500]

recently my rb20 32 has decided to sound like a wrx occasionally, it loses power when this sound comes up and then goes back to sounding normal at random, thought it was the spark plugs so i went and got a new set but the sound is still there, help!

Coil packs

Afm

Coil pack loom

Any order

sweet thanks, the afm itself or the sensor? because i cleaned out the sensor really recently

Its spark related. Gap the plugs down or try to pinpoint the cylinder at fault. If it does it at idle, disconnect each coil pack plug, one at a time, and see which one causes no change to the engines sound. I'm fighting the same issue but under load. I'll be sealing up my coilpacks, if no dice, splitfires it is.

thanks, seems like a much cheaper option to replacing everything, and yes it does it while idling as well

he doesnt need to gap nothing unless he is using wrong spark plugs.

The coilpack trick is probably your safest bet to try out
