You never know, I would just suggest calling up Joe over at Infiniti of Scottsdale, or Riverside Infiniti and just get them there.

[burgy]

looks like they are OEM parts...

[jeremys14]

i just ordered a couple from autopartswarehouse.com, they look legit. i'll i've really heard was stay away from deutscheparts on ebay.

[Small Hands y33]

I picked a couple these up a few months ago... its a oem part it has nissan on the packaging the fun part is putting them on!!

[jeremys14]

from what i've read there's a way to do it without removing the plenum

[Thebeezkneez]

yah not a fun job, mine needs it bad. along with the o2 sensors replaced among other things.

[jeremys14]

the behind the alternator route isnt too bad, but you better have skinny arms and hands.

[RajahCasti]

they are good knock sensors made my q into a beast

How do you know when its time for knock sensors? Recently my service engine light just came on. The car has plenty of power until it reaches full temp then feels like something is holding it back could it be the knock sensors?

[jeremys14]

easiest way is to go to auto parts store for free and get the codes read.

yeah the easiest way is to find a shop that does free code readings. But if your car feels like jerky and sluggish it could be the sensors or time for a tune up. My Q was weak until i changed the K.sensors and plugs

[jeremys14]

mine felt sluggish too, so first i changed plugs. then when light came back on it said knock sensors. but, for the pain in the ass they are, i would be sure that's what it is before doing them.

[RajahCasti]

buy the ones i got and yu will save money

[Thebeezkneez]

The jerking feeling is what i am getting. its almost a shutter. I am also getting like 8 mpg lol ( o2 sensors)

[jeremys14]

knocks don't give a jerking feeling. it just feels sluggish almost like a garbage truck won't stomp your ass in a race.

maybe one or more of your ignition coils are bad. once yu replace it it should stop. well mine did

well i hooked up a code reader to it and it gave a knock sensor and 02 sensor code. coils are worth a shot though. i have a whole parts car to work with fortunately.

[RajahCasti]

sounds just like my problem i had when i first got the car. Does it shutter a lot when it is on drive? But if you put it on neutral, or park it stops a little?

Yes exactly. it annoying as hell. Were you getting terrible gas mileage?

[mrduece88]

I need to change my knock sensor as well but have not done the research on how difficult it would be. But it seems like it isnt that fun from the little I have read... What is the best route/method to doing this?

[PJ_]

My Q has that jerking/bucking problem as well. I tried to figure out if it was a bad coil, but i went through and unplugged each coil, one at a time, and it didnt make any difference at idle or rev.... oddly enough, i reset the CEL, the problem still exists, but no longer does the CEL come up... its been weeks :(.

[LS14]

My knock sensors were going out so the car was sluggish. They finally failed all together and the CEL came on. Thing runs fine now. I'm leaving the damn things on as is since I can't really see a need for them. Rather spend my money on something more useful.

[mrduece88]

Yeah my Q runs pretty good it stutters once in a great while but need to get rid of my CEL in order to smog my car since I just purchased it three weeks ago.

[RajahCasti]

hopefully your o2 sensors are still good mine need to be replaced

[mrduece88]

Yeah my o2's are good I got a couple of codes when I scanned it and o2's was not one of them. But I did get one that I was unfamiliar with it read something along the lines of (IAT) my guess was intake air temp... but still not sure and was wondering if anyone knew for sure what that was....?

i think that is the wire connection connected to your air intake thingy check if it disconnected. i forget to connect mine when i replaced the alternator n it triggered the check engine light

Thats funny because I looked over all of that but it seems whoever messed with that last did not correctly connect it so it looked pluged in but actually was not. So thanks for the tip, plugged it in correctly and that IAT code went away. :biggthumpup:
