Low RPM - car shuts off
Picked up a 2011 g37 coupe about 40 days ago. Recently I notice the car has a bit of a rough idle but nothing to loose sleep over.
Started the car after work Friday after work-waited a few minutes - pulled away... stopped for dry cleaning a few minutes away, turned car off... Started car back up... Let it sit for a second- car started idling at about 400rpm and turned off. This happened several times. Called service they walked me through a few steps to finally start the car but couldn't take me in that day (no loaners). Finally got home (very rough the whole way)....
Saturday- same thing happens.. Todays Tuesday they have found NOTHING WRONG...
Any ideas, suggestions, thoughts?

rough idle.... car shakes more than usual? sounds like a misfire to me, i would recommend replacing the spark plugs and while thats getting done tell the person whos doing it to clean your throttle bodies out for you.

I second Ricio1991.
My car wasn't cutting off like this, but I did do a thorough throttle body cleaning and the RPM dips immediately went away. Start small and go from there. TB Cleaning is easy to do or cheap to have someone else do for you.

resolved- Computer issue (apparently). Dealership had a tech drive it for 2 days. Car stalled several times while he had it so he was able to understand exactly what Im talking about.
