OK, G35 heads!!!!!
Listen to this one...
Here is an issue I can not seem to get resolved...and my local Infiniti dealer is failing big time!!

I have a 2008 G35 Sedan. Man this car is beautiful. I have about 61K miles, now, and for the past 20K miles, I have
dealt with an issue. After driving and coming to a stoplight or a stop sign, at a dead stop for 12 secs, my RPM meter
takes a nasty dip to 400 RPM. It dips and come right back to the 750 RPM....Almost makes you feel like the car cuts off
or stalls. I have taken it to the dealer in NC and they keep telling me that it is normal and that the car will "hunt"
for an desired idle spot to settle. NO WAY! This car dips and bad enough that my passengers feel it. Babes riding with me
on a hot Saturday night, asks, "Did we just cut off?" Nah baby, that was the bass from the music. The most recent time
I took this car to the dealer, the service advisor says...."Hey, we just got a bulletin about this issue (March 2011)".
After servicing the car, the issue returned about 50 miles later. I even rode with a tech and he says..."doesn't feel that bad."
Ok dude....glad its not bad to you...since you are making the payments on this ****!!

I am really stuck.
Wanted to know if anyone else had this issue? Was it fixed? If so, what fixed it? If you are going
to say idle relearn...I did that a few times with the dealer and no fix.

INFINITI HEADS!!! WHO CAN HEEEELLLPPP!!!!

 

I'm curious as well.

I still have this problem, wonder if it was ever resolved.

 

most likely you need to have an induction cleaning (aka throttle body cleaning).

I agree, most likely needs a tb cleaning.
