This was the first thing I replaced! Previous owner had it duct taped, but did a horrible job. I replaced the MAF this past weekend. The hesitation, hard start, and stalling seems to be gone! It seems to have more pep as well! That pesky misfire code disappeared, but it still idles a little rough. I'll keep this thread posted on what I find.

Little update. Idle was really rough yesterday, sitting at 500rpm, then bogging down to a stall. Decided to unplug the MAF sensor and the idle went back to normal! Guess I'll start with replacing the sensor and go from there.

Hello all, Recently, my '00 Qx4 has been having a few issues. SES light came on, so I checked it with my Amazon OBD2 scanner. "P0300 random misfire". It's been randomly stalling on me at low speed, usually when I switch from forward to reverse or vice versa. At times it has a hard start. There is sometimes a hesitation if I come off the accelerator. It idles decent. Then, yesterday I was driving with a heavier load than normal (3 extra people and some luggage), outside temperature in the 30s C, the vehicle stalled twice within 10 minutes. It felt like I had lost all power and couldn't accelerate, and the engine ran until I pulled over and came to a stop, where it would then stall. It threw another code, this time P0100, to go along with the misfire code. MAF sensor or circuit. Did some digging, turns out this could also be caused by a vacuum leak. Where should I start with this issue?

@Mrelcocko I have this, but only notice it when slowing down between 12-18 mph. I replaced the lower control arm bushings with poly bushings but skipped the upper trailing arms as I ran out of time that night (those old bushings are a b***h to remove haha). Would the horseback riding stop with the replacing of the upper trailing arm bushings?

Daytime running lights. They are actually your high beams at half brightness that come on when the headlight switch is off.

FINALLY bought and mounted these rims.

I bought my Pathy and it had the same problem, It turned out to be the distributor bearing going bad and eventually seizing.

Hey all, Did some Google searching and found this link! https://cardiagn.com/nissan/

UPDATE: I noticed that my radiator had a small crack in the top, plus about a third of the neck where the upper rad hose connects to was broken off. A new rad was put in but it didn't do anything for the coolant temp gauge. I didn't have time to go to the local pick-a-part the other day, but i did a continuity test as directed in the FSM. I didn't get continuity, but figured it might be because the probe wasn't making contact properly inside the harness, so i shoved it in deeper. Doing that either cleaned or opened the connection enough for the wires to make contact with the sensor, because the gauge is working properly now lol At least my entire coolant system is upgraded haha! Thanks for the suggestions guys! -Dennis

Thanks for the help Slartibartfast! I am heading to the local pick-a-part to pick up a new instrument panel

Mine only has the 1-wire in that location, whereas my 93 has both together. Not sure where the other one would be? However, I checked the sensor with my multimeter, and its reading correctly.

Hi all, About a month ago, the coolant gauge in my 99 Pathy started acting weird. Examples include jumping to running temperature at startup, dropping to cold, spiking to hot before settling at running temp. One day on my way home from work it started at running temp (after sitting for 8 hours), spiked to hot about 3 minutes into my drive, dropped to cold 2 minutes later, rose to running temp like normal, then spiked to hot again just before i got home. Just this last week it has started to be somewhat normal except for spiking to hot and staying there about 5 minutes into my drive. Replacing the sensor located at the upper rad hose didn't do anything to fix the problem (maybe that's the wrong sensor?). A mechanic friend suggested it could be the thermostat not opening properly so we replaced that as well. Still no change. After doing a bit of research i can only come up with a few things that might be the problem: - bad replacement sensor - plugged radiator - sensor grounding out - water pump is on its way out. Any one have any idea whats going on, or have had this before? Any input on how to proceed is much appreciated. Cheers, DN

Update: SHE'S ALL FIXED UP!! Replaced the distributor, and now she's purring like she should All she needs now is a battery that holds power and I have a 'brand new' Pathfinder that i purchased for $600!!!
