Car stalling when starting up

[jayrishi]

Hi I have a 350z 53 plate I changed the battery last week as last one died. Since then when firing up the car it starts then if I turn it off and back on it starts but the Revs drop and feels like it’s going to stall

 

any help will be appreciated

This is exactly what mine is doing as well. Mine has been sat for a long time so had a new battery fitted. Do you have an engine light on as well??

No engine light which is strange, not sure what the issue is to be honest

I would as first action look up and carry out a throttle position and idle control resets *warm engine
