I got codes P0305 (cylinder 5 misfire) P0130(o2 sensor bank 1 sensor 1) and P0150(o2 sensor bank 2 sensor 1) autozone pulled them for me. I know I need a tune up, so Im getting my spark plugs changed with NGK's V-Power.

I want to know if. . .
1) replacing my spark plugs will resolve the misfiring?
2) these are two different o2 sensors?
3) if its just one, is it the one on the front passenger side?
4) is this a DIY type of job?
5) there's anything I may want to do for my tune-up?

I've done my oil change/oil filter and TBS cleaning last week myself, and I am changing my air and fuel filter today. . .

It could be your coil pack or fuel injector that is causing the misfire. Check on those. Mine had a misfire on cyclinder 5 and my CEL was blinking, so I thought it was my coil pack turn out to a bad fuel injector. I replaced the injector and now my max is running fine.

I'll look in to that thanks. I think i may have to replace all my coil packs and fuel injector eventually.

1. Unlikely, unless they were gapped very wrong or damaged.
2. yes
3. --
4. yes
5. pcv valve (if it's sticking or original equipment), drain and fill radiator with new coolant/water

Ok, since these are 2 different o2 sensors, where is the second one located?

one sensor is located near the radiator and the other is near the rear axle i believe i had mine changed 10 months ago and if u have to change one u will 100% change the other change both of them together its ur best bet

I'm thinking of changing all three o2 sensors and am looking on ebay to purchase them. From my research on the org all three sensors are the same design, so im thinking of buying 3 of these http://cgi.ebay.com/ebaymotors/ws/eB...m=200257056438

Would this be okay?

they're ok, i bought them from a different seller stating they were ntk...doesn't matter because they're cheap and work right. iirc the pre cat o2's are the same but the 3rd one is different (different function).

I paid around $65 shipped for the two o2s on ebay, don't worry about the third one, it doesn't really go bad as often as the fronts as long as the cat is working correctly you should be okay on that one. If you don't have a Haynes manual or Chiltons, you should get one also get a multimeter, you can check the continuity rating on the coil packs to make sure they are working, or pull the plug off one at a time to see if you hear a change in the rpm. Usually if there is no change if you pull the plug off, that is the bad one(you usually will also get an ignition code on the cel).

universal sensors are a bad idea. get some direct fits for ~$50 ea.
PM me if you don't know where

You were absolutely right. In the midst of changing my spark plugs i found that one of my coil packs is bad, its broken. i believe its cylinder 5 like yours.

5 cylinder went on me too. Got a few extra sets laying around just in case now.

The first thing to always check though is plugs. Ive seen on a few occasions, the ceramic portion of the plug has cracked, probably thru shipping, or installing them with a cordless impact. That can cause an annoying intermittent missfire, thats very difficult to track at times! Often it doesnt miss enough to trigger a CEL, so your SOL gotta diagnose each cylinder.

If you have a Fed spec maxima, you will have 1 o2 sensor for each cylinder bank, therefore, you will have 2 in your y-pipe, just after it connects to your exhaust manifold, and if you have a 97-99 you will have one just after the main cat, or if you have a 95-96 you will have one in the cat. The rear o2, is not claimed to effect gas mileage, because it is strictly there to monitor if the main cat is doing its job.

The two important ones are the front drivers side and front pass. side. Its not overly hard if your somewhat competent. You'll need a 22mm wrench..or 15/16th (7/8th cant remember). soak the o2 in penetrating fluid of your choice, and let it sit for atleast 20 minutes, give it a shot, to see if it breaks loose, if not, i would take it to a muffler shop, have them break it loose, or just get them to do it. Personally i had no problem, but some people do.

I replaced both of my front O2s with Bosch ones that where universal and I had to splice the wires (the splicing stuff comes in the box with the sensors). You can go and loan an oxygen sensor tool from any car parts store around you and when you're done with it return it and get all your money back. I changes mine myself and it was very easy and fast, other than the time for splicing.

+1 on the PCV and the fluids
