Trace the plastic vacuum lines running from and near the passenger side of the engine. May be melted/broken/disconnected. Look at the vacuum harness and individual vacuum lines under the passenger side of the dash. Also, the plastic vacuum reservoir which may be cracked - the location varies by year but I believe that the 99 is between the inner and outer fenders on the passenger side.
