Solvent peak tailing

Good morning,


I'm new at method development and my solvent peak continues to tail causing me to pick up unnecessary area in the early carbon ranges. I am on an 8890 GCFID and currently have the Agilent HP-5 30m x320umx .25um installed on the front. Heater is at 280C with a constant pressure and flow, 400 air and 30 H2. I've attached a picture of the inlet settings and chromatograph. There is no indication of a leak at the inlet. Can anyone help me with this?
