When you push the gas the car falls on its face. Idles just fine but as soon as you push the gas it acts like it's starving for fuel or air one.

Hello, I'm Danny.

The first thing I would do is check the fuel pressure. It sounds like you might have a weak or defective pump that is not providing adequate fuel pressure. If you don't have access to a fuel pressure tester most auto parts stores have a tool loaner program that can rent you one. Here is a tutorial showing what is involved:

The fuel pressure specification for you car is 44-50 p.s.i. Let us know after testing and we'll go from there. Hope this helps and thanks for using 2CarPros.
