getting code p0300 & p0304

[joelala]

I have a 2001 Nissan pathfiner and while driving I get the check engine light flashing and the vehicle loses power then shortly after the light will go off. It has happened twice in about 2 weeks. I have scanned the vehicle for any memory codes and came up with p0300 & p0304. If anyone can offer any help it would be great.

I would check all of the following:-Improper spark plug -Insufficient compression -Incorrect fuel pressure -The injector circuit is open or shorted -Injectors -Intake air leak -The ignition secondary circuit is open or shorted -Lack of fuel -Drive plate or flywheel -Heated oxygen sensor 1 (front)
