  • Hi Fernando.

    First, How are the ignition components -- the spark plugs, spark plug wires and the distributor cap?

    Have the fuel and the air filters been serviced?

    Have the vehicle scanned for diagnostic trouble codes (DTCs).

    Check all the vacuum lines for leaks.

    Has the timing belt been replaced? Check the timing marks to make sure the timing belt has not slipped a few teeth. It should be at 5 degrees before top dead center.

    Test the fuel pump pressure and the fuel pump regulator.
