does it run with the gas pedal down and die at idle?? if so the idle aircontroller is bad

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

opined in news:H4Odnduu5O3    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 (abovethe right tire) and its a box that has a bunch of wires going to it and onerubber hose going to the throttle body for vaccum.
