A large 219 peak may appear during tune when the source is cold.  In this example, the 219 peak was 225% or the 69. This is especially prevalent after cleaning source or after a venting of the instrument.  Additional troubleshooting may require ohming out the heater/sensor assembly and checking the integrity of the wires. Verify that the transfer line is heated and on.
