I have a 2008 G35 with this exact same issue. I have taken it to 3 different mechanics, including an Infiniti dealership, and have gotten 4 different diagnoses. Meanwhile, the problem keeps getting worse. First mechanic (and third...took it back to him after going to the dealership), said that it was a bad valve timing gear(?) and would cost about $700 to replace. Then, I took it to Infiniti and they said it was something else (I'll post up what exactly they said, if it'll help fix this issue) that would cost $1800 to patch and $4000 to fix! That's not a misprint. Four large to fix a car I paid $9500 for. Of course, this did not happen. I told the rep that if I did $4k in damage in a wreck, the car would be totaled. I asked if they could just increase the idle speed since the only time the car stalls is when it's warm and at idle...and only does it intermittently. Of course, this would be far too simple (and cheap) for the dealership to do, so they didn't even humor me and try it. Took it back to mechanic #1 and he gave me another diagnosis! Then, my wife dropped it off at this other guy, today. I didn't trust this guy at all because he had told me that the fix for my Jeep would cost about $2000, when all I had to do was put on a $70 steering stabilier shock. Anyways, this guy is her nephew's stepfather and she wanted to give him a chance. What does he say? The transmission is bad. Well, of course it is...lol. This is why I don't trust him, specifically, and mechanics in general. It kicks out a code, the guy plugs it in to the diagnostics computer and arbitrarily believes whatever the code says, without exploring the possibility that the car's computer might be compensating for the fact that the car is shutting off at a time it's not supposed to, and kicking out a code. Either way...I've got to do something. I want to start with a simple spray fuel intake cleaner, then increase the idle speed, either manually or electronically. If that doesn't work, then replace the cam position sensors and crank position sensor. If anyone knows a better way or has had issuse with this, I'm all ears. There was a recall for this very thing on earlier models, but no-go with this year model.
Thanks
