    I am about to replace my catalytic converter on my 2001 Xterra and would like to hear suggestions on what bolts would be best as replacements?
  2. Repair Questions
    New to the forum, first time posting. I got a 2010 Xterra Off Road with a check engine code for the bank 2 catalytic converter failure. I’ve had it for awhile now and want to get it fixed without paying over a grand to replace it. I’m confident enough to replace it myself but I can’t seem to...

    My 2004 XTerra was made for California emissions standard (I'm in NY), which means catalytic is built into exhaust manifold and it's extremely expensive to replace. I suspect there are other differences as well, like a more sensitive O2 sensor. I'm shopping for a newer XTerra (2010-2015), I...

    2003 Xterra SE 6-Cyl I recently had the engine tuned-up (gaskets, wires, lines, spark plugs, etc. replaced) after what seemed like oil leaking from the gaskets. Within 25KM of leaving the shop, the engine light came on, and so I brought it back. They determined it was the Catalytic Converter...

    Hi there, I received "misfire on cylinder 1" codes and took it in and found out that a cracked spark plug coil on cylinder 1 was the cause. This is the second time this has happened in approx 2.5 years. They also found several coolant leaks and I am getting a couple of codes stating that my...

    I have scoured the FSM, but can't find the exact position to jack the A/T so I can remove the rear engine mount. It seems necessary to remove to get the cats in and out, at least to get them in, as I can torch/saw them out. I know many of you out there would know this, and I would like to know...

    Some back story, I have a 2004 non supercharged 2-wheel drive xterra w 159k miles. A few months ago I was getting some really bad mpg and my SES came on, I got it scanned and my engine bay 02 sensors were tripped as well as the ones near the catalytic converter and a fuel level sensor that comes...

    Have a 2002 X, 3.3 non-supercharged 4x4, auto tranny with 210,000 miles under it. It will start perfectly and idle perfectly, when you try to drive it it has no power, and won't take gas only in one spot maybe 1/4 of the way down but thats it you can floor it and it bogs down and slows down...

    I've got an "02 Xterra 4x4 that is running poorly. I need a new catalytic converter. I have the understanding that it has 4 catalytic converters. I was told that it was the driver side cat, but i was never told if it was front or rear. How can i figure that out? Also would it be possible to...

    So I've got a 2003 3.3L 4x4 and I am getting the P0430 code on it. So it obviously has to be a bad cat or a bad o2 sensor right? Now I also am feeling a vibration or rattle when initially accelerating at about 2k rpm. Does this imply that it definitely is the cat that is shot?

    2001 3.3L w/ ~170k miles. I replaced a cracked right exhaust manifold and approximately a month later, thanks to the wonderful state of California, I'm due for smog check/inspection. Had no SES prior to smog but low and behold "they" were kind enough to generate this one for me: P0430 Catalyst...

    My name is Jenn, I am new to the forum. I have a silver 2000 V6 2wd Xterra. It is giving me grief at the moment. I love this car, it is my baby, but it is jerking really bad. I am thinking it is either a manifold leak or a catalytic. I am pretty sure it isnt the MAF sensor, as we just...
  14. New Member Introductions
    I'm new to the site. I've owned my SE V6 4x4 2000 since it was a year old with 35k. It now has 162k but not running anywhere near where it used to. Currently I'm in the process of removing both catalytic converters due to an extremely sluggish engine. The truck stutters so much that it shuts...

    Background Info: The girlfriend and I have a 2005 Xterra with a check engine light on. We have a routine where she takes her car to a particular garage for service, and when they throw her an extravagant price to fix I end up doing it myself ( yes I do think its a gender thing). This time...

    I have a 2000 Nissan Xterra 6cyl 2wd. In the process of removing the passenger side rear o2 sensor I managed to completely strip the nut. I bought the special o2 sensor wrench. I sprayed it with PB and let it soak. Still nothing. The angle was PITA but I got the wrench on there securely and gave...

    I have an 02 xterra not supercharged. I have had a recurring error code problem- both catalytic converters operating below standard and the knock sensor. I had them reset and drove for several days before the codes came back. My thinking is that these are likely related error codes, maybe a...

    Hi, I got great info from the forums, which helped me fixed some problems with sensors in my two Xterras. So I'm trying to return the favor and post some hopefully helpful hints myself. Recently I bought 2005 Xterra. The guy sold it very cheap. Pretty quickly I found out why. The car had...
  19. Repair Questions
    So I guess I will start off with describing my xterra. It's just a plain 2005 with the SE package, 113,000+ miles mostly highway, that I bought from carmax last June. I have taken it in places I definitely should not have been with a near stock vehicle but as most of you know, this thing is a...
