I got a 1997 Nissan Pathfinder SE, I had issues with it on Tuesday in which I was going into work and notice the temperature slightly increase then increase between halfway/three quarters. I got into work fine, told myself probably low on coolant. However on the way back home, I notice the car ...

Nightmare is over! So here is the solution and symptoms on my 97 Nissan Pathfinder SE:

On 2022 of December I got MIL (Check engine light) plug the OBD and it came out Bank 2 Sensor 2 o2 sensor. P0161 (o2 heater Circuit) in which ran good until 2023 the car began to rough idle.
Eventually the car ...

There's no real equivalent to a P0101 on older stuff, so P0100 covers a multitude of sins, open, short, and malperformance. The ECM can't tell you which, but a voltmeter generally can. Check it against the specs in the FSM, you may actually have a wiring issue and not a bad MAF. Not that cleaning ...

I got Bosch for the sensors in which according to some research they are the OEM suppliers for the vehicle year 1997.

P0100 has been giving me issues in the past as well, battery was completely disconnected when I swap them, connected the positive terminal first then the negative. I will give the ...

Situation update - just finished installing all 4 sensors, codes disappeared as I had the full battery disconnected. The car did warmed up really well, no codes after operating temperatures.
However once I was pulling off the drive way the car did began to sputter and gained its power. However once ...

Appreciate the information. As I was swapping the o2 sensors I was able to tell that both of the passenger side was carbon present. Specially the down stream sensors, however once I got to the driver side I notice that the protective sleeve for the down stream was stripped and wires were exposed. No ...

I have a 97 Nissan Pathfinder - swapped the spark plugs on May 2023 (Bosch), the car ran without any issues until December 2023. I got an MIL light, plugged the OBD - it started with the front passenger sensor o2 giving issues, eventually through the time all 4 gave out. Around the same time of May ...

DIY-able if you have good tools and good skills… My go-to is usually AP/Eastern Catalytic, decent price, good quality, and (very importantly) they usually fit right without any screwing around.

Thank you @VStar650CL.

I apologize for being high maintenance. Although I’ve done a wide variety ...

There are two parts to my sad story:

Part one: May 2023 I swapped my O2 sensors from my 97 Pathfinder. OBD-2 only picked up Sensor 2 bank 2 error. I decided to have all 4 sensors swapped with Bosch, everything was fine until November the car would take turns on selecting with sensor to throw on my ...

Oldie but goodie - situation update now my Bank 2 (sensor 1 + 2) are not getting shot up + today I discover the Sensor 1 + Bank one is getting read too along with the EGR + MAS Flow code.
I think my car needs an exorcism at this point.

Thanks! Unfortunately I will be draining through the bottom radiator hose since I got into an accident a few years back - the water cock is blocked (its an after market radiator as well).
I plan on doing this hopefully this weekend since we are suppose to get some rain next week here in So Cal.

I have been putting this off for a while since I have the heads resurfaced. I started doing the flush before I was able to get it to 3 cycles. The last time I did it the water was still dirty, however I promise to do it again but always got something came up. Now I want to do this before the wet ...

Thanks for the info, I think I am going to take it to a mechanic. I am tempted to see if I have a vacuum leak somewhere if that is the case, not sure how I went from 15 down to 7.

An old timing belt that has been stretched and worn old with age, will retard your timing.

Ugh!!!! So I have ...

Too much advance will make the ECM dial back the power when it detects knock, so that could definitely limit your performance. You'll need a timing light to set it up perfectly, and the engine must be at the proper idle speed defined in the FSM. However, you can get it close just by turning the ...

If the engine revs normally but those RPM's aren't being translated into movement, that's a transmission problem and not the engine.

Sorry, it is more like the engine feels sluggish, wonder if it has to do with the spark adv been at 7 degrees vs been at 15 +/-2 normal range. I did refuel on ...
