03' G35 turning on/off engine, VDC light

[may88]

My 03' G35 auto sedan is turning on/off and the service engine and VDC light are on (the VDC light has been on forever and never caused any problems) problem started when I floored it and then had to stop suddenly. The car turned off and had to push it back down the street to my house. My brother changed the carburetor fluid and connection to air box and then after some hours it turned on and drove around but when got back home and tried to turn it on again would not turn on. Tried for about an hour and after multiple attempts and it cooling down it turned on. Replaced the fuel pump but still having the same issue of it turning on when cold and driving around but not turning back on.

Tried: replacing fuel pump, carburetor fluid, connection to air box ok.

ANY SUGGESTIONS????? PLEASE HELP!

There is no carburetor on a G35 or any car for 2 decades. So what fluid are you talking about changing? You probably need the Throttle body replaced because the TPS sensor is shot.

Either throttle body or cam phase sensors. I'd put money on the throttle body though.

carbeurator fluid?!?!?!?!?!?!?!
VDC light may be on due to a bad wheel speed sensor, or low brake fluid. Get it to a dealer or competent shop
