When I step on gas in my G37 the throttle response is a bit lagged. It has increased ever so slightly over the past 6 months. Can someone explain what the cause of this might be and any preventative maintenance suggests I can employ to prevent it in the future?
There are no codes being set in the PCM and no check engine light.
I run the recommended fuel type of premium unleaded, follow all maintenance intervals and use all recommended fluids suggested by the manufacturer.
