2. i have attached fuse box picture….one relay by look seems damage….. as per indication on fuse box it looks battery…….but car can easily start with no issue….can you please guide me which relay is this and what it do.

The one marked battery is not a relay its the main battery fuse. If the car is starting then
the fuse is good. The pcv Lives right under the throttle cables by the throttle body. The
black hose runs underneath the throttle cables and is threaded in.Throttle cable means the two solid silver metallic wires connected with accelerator … that open the throttle mouth by depressing accelerator ?
I have attached picture by red highlight ….. is this same you are telling me?From what I’ve read, I am going to respectfully disagree.
You see that rectangular thingy near the top right corner of the photo? It has two hoses coming out of it. There are two more hoses underneath those top two hoses, and the PCV valve should be connected to the rearmost lower hose, (the darkest hose in your picture), threaded into the intake manifold.
Also, I have a small concern about the following photo.
Almost in the exact center of your photo, it looks like a hose is disconnected. You might want to hook it up again if you aren’t aware that it’s been unplugged.
Here is a picture of the pcv supposedly. Hard to find this sucker.

Dear Mr. Eric,
Car: Infiniti QX4 2000 model
My father has replaced gear box in past.
When i drive in city or smaller distances, it feels nothing…..pretty normal… but when on highways i drive in high speed…some speed above 80-100 i clearly feel gears running on steering and by sound…………..what will be that—is it normal? is this something to worry about? any solution?Similarly, MECHANIC repaired steering box…it was leaking from somewhere before that……normal driving is ok…but like in zero speed and rpm…when i turn steering left right….i listen machine sound increasing…..what is the reason and how can i solve it…..as there is no leakage now…
kindly help….

That area we thought was the pcv circled in red is not the pcv but just a fitting. Evil-I
shows the pcv( thank you Evil-I 🙂 ) Hopefully between the both of us we can find the PCV.Could you post a video of the sound? When the power steering leak was fixed
was the correct power steering fluid used? see if this link helps.https://www.ericthecarguy.com/faq/diagnosing-noises-in-your-car
Dear Mr. Eric,

You may have gotten cleaner in the intake when you cleaned the TB. If the jerking does not stop
there may be another problem. No check engine light on or engine light flashing? Change the PCV
on a cold engine.there is no any engine light or flashing during drive. Also speedometer remains normal as before…
Yes….there are small internal jerks that i always notices when car is in gear and stopped in traffic.In neutral, how much race i give no issue…how much idle it remains i don’t feel that jerks..
But that jerking started only after using MAF cleaner for throttle and i also cleaned MAF without touching inside or sensor……
Please help…..will it stop after some time…or any solution…..will this cause any problem?
You let it dry when you cleaned it. Check that it is plugged in or any of the pins
did not get bent.Yes, dear college man I dried it properly in normal environment. I lived in Middle East UAE and you know seasons remains hot here. So it was dried completely before i installed it back.
Connector i rechecked….i saw no issue.Also that vibration exist only when car is in gear mode and can be feel when in gear and slow or stopped with gear in.
but what i noticed yesterday, i hope it is jerks of 4WD because i checked just for no reason my 4wd and turned the knob to Auto or 4wd….i listened no sound of 4wd which comes from car when you engage for 4wd….like Dddhuubbb…..
Also after turning knob, i saw continuous indication of front two wheels and central lock blinking while back two wheels remains unblinked.this condition remains same yesterday…whenever i start my car….
but today morning there is no such blinking but 4wd dhhuubb sound is not there…means 4wd is not working…
So i hope that this the main issue………
