Recently my Pathfinder had been going off by itself while it's idling. I initially thought it had something to do with the fuel pump, but I just changed that. So I filled my tank above half tank just to see if it was the fuel pump not getting enough fuel, but to no avail. I then thought perhaps it had something to do with the engine or electricals. Checked all the ports, the fuel filter etc. Still it still kept going off. I didn't think to check the air flow into the engine... I just didn't think the flow was insufficient. But alas there was a leak detected when I took it to my mechanic's workshop - the leak was so inconspicuous, but quite significant. It took just changing the rubber sealing - a less than $1 fix🤦. It just proved how important air was to the engine performance.
