Car will not excelerate and it cuts off when it reaches operating temperture. The fuel pressure is too high also. I've changed several parts, the engine computer, fuel pressure regulators, throttle position switch, spark plugs and wires, rotor button, throttle switch and it still doing the same thing. What do I do to correct this problem? I will greatly appreciate some answers I have tried everything.

Check the fuel return line to the tank for damage!

Check your catalytic converters for either a melted or broken bed condition.
