My car has been having a weird oscillation and dying probably once a week. It will drop to 400RPM grumble and then just cut out in the same second. No codes being thrown no obvious signs except for the -when in park you can hear the engine oscillating a little strange, very faint.

I was going to replace my plugs and coils and see what the did. Any ideas what else to look for?

Also happens when the is under heavy load, like turning the wheel all the way a direction, AC ON, and idling/moving.

My second guess is fuel pump?
