Does anyone know why my 2003 Saturn LW300 wagon stops when I remove my foot from the gas pedal and I cannot shift into any gear?

 

It could be a number of things .... so to guess what it is with your car would be just that ..... a guess. Lets say its a vacuum leak or a throttle position sensor .... would you know how to find a fix either? If not you might want to bring your Saturn to someone that can. Oh and that does not mean Al's Auto and Apple Cider Sales.

 

You really need to read the codes on that car. We'll go from there. My first guess is a weak fuel pump or pressure regulator.
