Engine Shuts off when putting Drive or Reverse [Help]

Hello everyone,

I own a 370z 2014 Roadster, I have an issue where if I changed the gear while stopping (while still cold) the RPM will drop down (400-500) and the car will vibrate and goes right back into position (600-700 RPM).

If the car is warmed up the engine will shut off when putting into drive or reverse.

I've sent the car to the dealership and they fully examined the car and told me there was "no code" and they didnt find what's the issue.

I searched online and there's like alot of reasons like torque converter, vacuum leaks, throttle position sensor, crankshaft position, transmission oil situation, fuel pump/injectors, spark plugs(misfire) and alot more.

Anyone had the same issue on their 370z?

UPDATE: I went for a quick ride today after I warmed up the car, the engine didnt shut off when changing gears just a little vibration due to RPM drop to 400-500.
Once I accelerate I can feel that the car jerking.
Could it be a vacuum leak? and how do I diagnose that?

PLUS: My car has straight pipes, does this affect anything? I had them for more than 2 years

Thank you,
appreciated.

Clean your throttle bodies.

They are clean, I double checked them

MAFs can cause problems when they get dirty. Cleaning is a fast and easy job - a can of MAF cleaner, a screw/nut driver, and 15-20 minutes.

I've cleaned them yesterday and the idle went up to 1000 and the vibration disappeared. After I did the relearn procedure for idling the RPM went back to normal the vibration came back when changing from P/N to R/D in gear.

So the issue is still there.

Just a quick update, I went for a test drive in the car and it jerks like crazy and now theres a clicking sound whenever I put D or R from the engine bay.

Its the torque converter, incase it happens to someone.

Case Closed :)
