If it has no power at full throttle when in gear, and it dies check the MAP sensor on that car.

opined in news:H4Odnduu5O3 snipped-for-privacy@comcast.com:

Fuel squirting from the line does not mean fuel pressure is good.

Besides the MAP sensor, a likely suspect for the symptom is the fuel pressure regulator. The typical test is to remove the vac line to manifold and see if it has fuel in it. If it does, it's bad. If it doesnt it still could be bad.

After 15 years, just install a new one.

I know that the map sensor is usually on the right side finderwell (above the right tire) and its a box that has a bunch of wires going to it and one rubber hose going to the throttle body for vaccum.
