My 2004 Pathfinder has made this bad engine noise twice after just getting the oil changed and the fuel filter changed, now I'm parked and have no idea WTF is happening, sounds like fuel injector? I thought i heard springs busting loose the first time, then it drove perfectly fine until today when i had to step on the gas in a hurry, any ideas?
