Hi Guys,

I've recently encountered a strange behavior from my G. I will be at a stop light and the RPM would be a little below 1K then it would spike up to 1.5-2k on its own

It feels like you tap the throttle really quick and the RPM would rise close to 2k.

The strange behavior has caused me to stall a few times when I would let go of the clutch to accelerate due to the RPM spiking then dipping low below 500 rpm

also:
The car starts up fine in the morning when I head to work, But at the end of the day when I go to start her up the RPM will dip low and the car will die, resulting in restarting and giving it a little gas to stabilize the rpm at idle.

I am simply wondering if this is because of the battery or something else?

couple weeks ago I left the dome light on and it wouldn't start.

Was curious if anyone else was experiencing this strange behavior?

Thanks

This should solve it if your TBs are dirty, it did for me. But how many miles have you got on your '12? It seems a little early for them to be that bad already...

Thanks for the feed back about my situation. I bought the vehicle cpo. It currently has around 15k miles. Is the DIY simple? I heard from people i asked around that I could trigger the check engine light if I remove the throttle body? I Asked the local Nissan and Infiniti dealerships and they quoted me roughly $150 to perform A throttle body service, sounds kind of expensive to clean two throttle bodies.

Thanks again for the feed back

Extremely easy. I did it in around an hour with a rag and some TB spray.
