Need the help of the .350z community. PLEASE

I own a 2008 350z base model. I do regular maintanence on it (Oil, Brakes, Suspension, and etc)

Recently I had a really bad issue. At a stop when I pressed the gas pedal my car started jerking like with someone is learning to drive stick. I shakes likes it's trying to go and is choking after being towed it went away works fine.

Dealer says bring it if it happens again. Fuel pump ok fuel filter is non servicable no check engine light ever. help

I have racked my brain to find out what it is and don't want to wait around to happens again especially don't want to be on a hot date and look like a jackass either I have not done a tuneup yet or the throttle cleaning service so I just don't know even machanics are not sure what it could be and I feel like its a time bomb worrying when it will fail again and don't want to wait but I want to fix it so it never happens

Any help is greatly appriciated ill answer questions any one has to help fine the problem.

Thanks

 

mileage?

 

And this only happens for a minute right? After warm up it goes away? Read the thread about stuttering. I think it's about oil viscosity. Did you change to a different oil?

 

The obvious thing IMO,would be to start by putting some additive in
your gas.May be something clogging up your injectors.When the car warms up
it gets better.The oil viscosity as already mentioned,could be a factor.
But in L.A.'s temp?Something is expanding when the car heats up that
improves the situation.It could be a sensor that is starting to go out.
How old is your car/miles?
