My car fires up on start up but it is very cold running. If you even think about touching the gas pedal it will fall on its face. But once its warmed up it runs ok. So I am assuming there is a sensor that controls timing for easy start ups. Am I on the right track and if so is this sensor in the water jacket somewhere.

Details, details? Car, engine, ignition, induction.

Not enough info here... Too many variables based on info given....

The car is 82 280zx she is stock as far as I can tell. She is non-turbo.
