I have an 06 g35 with 150k miles on it. I’ve been having an issue with the car dying at red lights on me, however it starts right back up and I have no check engine light after. I replaced my plugs, coils, even a leaky valve cover gasket and seals, my cam sensors, and just replaced the fuel pump. The car occasionally hesitate under load as well. Im lost as to what the problem is, has anyone had the same issue or an idea on what it is?

I would start with your MAF based on the symptoms that you mention. What type of air filter do you run? Start with a cleaning of the MAF with a MAF spray cleaner. If that fails you might try testing or replacing the MAF.

May consider cleaning your Throttle body at the same time as cleaning the MAF.

I’ve taken my short ram intake off quite a few times and have cleaned them both 4 or 5 times in the last two years. I could be wrong but wouldn’t a bad MAF throw a light?

I have a short ram intake and replace my filter every 6 months approximately, haven’t had any issues with it. Is it possible the maf would only act faulty when it warms up? The car only does this when I’ve been driving for a bit although it is very intermittent it hasn’t happened in a couple weeks. Car runs perfectly fine otherwise doesn’t run rough at all
