Okay, Finally got my car back.

Report reads: Code: P0300 - MULTI MISFIRE.
REPLACED FAILED CRANK SENSOR
Part: CRANKSHAFT POSITION - 23731 - JA10B

Anyways, Happy to have it back ... Thanks fellas..

 

is that the same as the camshaft position sensor?

CAMSHAFT: 23731JA11A
CRANKSHAFT: 23731JA10B

Looks like both could be the same sensor, but in different places.

 

so that could be my problem too.
the same sensor that you had go went on me too.

question for you. did you feel the vibration at any rpm. for me it does it around 1k rpm when i put it into gear or start driving it.
thanks.

 

wait how bad are your vibrations? I get them a little when the car is cold, kinda like a random shudder from the engine.

 

it not as much as a vibration its a ticking or clicking noise or like the exhaust shield hitting or the belts vibrating. sounds like its comming from the front of the engine area.

i dont know. thinking about taking it to the dealer i guess. even though they will shaft me and say its not warrantied.

 

Mine was not random, you can hear/feel the misfire. Also hands on the gear during idle and moving slowly, felt as if the gears are touching the road.

I am sure you guys will know if this was the case in your cars. Also while accelerating you will feel the slower pick up.

And all this not while the engine was cold, even after couple minutes of warm up.

 

i have a sound clip
this is what mine sounds like.

 

Dude, mine had the same vibration, would suggest to check your timing or this sensor for Code: P0300.

To answer your question, yes there was more vibration felt at lower RPM, sure at higher RPM we don't feel as much.

Mine is a stock car, looks like you have pimped up good.

 

Yikes...

 

dang! nissan did a recall about 4-5yrs back for bad crankshaft sensors in almost EVERY vehicle.

 

so took it to the dealer this morning went to dunkin 50 feet away from the dealer while pulling out from the parking lot it was still doing it.
parked at the dealer..
went inside got the paper work..
ok lets hear the noise start it up nothing. turned it off on again nothing..
WERGWESDFJIBSDFHBEIT#%HYV( ETRBNEH*(SYSW#(T*G# YHWE#*(@%TR( #@T#(YHI*YE$HBWE$HB
waited 30 mins at the dealer started back up nothing.
ended up leaving it there for the day see if it comes back.



ok so got a call back from the delear and like i said. HA
they were able to duplicate the sound. and guess whats causing it. the pulley since it is not a oem part it is not covered and i can replace it back to stock and see if it makes the sound again.

although i explained to them that i know another completly stock G had the same noise and it was the crankshaft position sensor. which was replaced.


ya that was their answer.
now after thinking about it. honestly once they took the car up to the lift i dont think it made the noise or did they even hear it. as soon as they saw the pulley it was a wrap and they just said ok. thats the fault w.e

because honetly while i was there for half the day it ran perfect nothing irregular. so they didnt hear anything then a couple hours later once the took it into the shop and looked under the car and their like ok its the pulley so thats their excuse and thats it. no need to look further and since they didnt bother looking.

also they better fill up my coolant bottle. with the oil change it should be included see how that goes.

infiniti G=win.
infiniti dealers=fail. except for riverside which i hear all you guys are getting good issh from, and everywhere else is just not what its supposed to be.
