Recently bought a 04 Trailblazer and am trying to fix some problems. SES light is on and throwing a P0455 code. Twice after filling up with fuel, I went out to the truck and noticed a strong gas smell in the vehicle. The smell is not there anymore after a day. It also seemed to be lower on fuel (not sure about that). Would this suggest a bad vent solenoid, leaking filler neck, broken EVAP canister, etc.? Any comments would be appreciated.
BTW - this is my first post. Great website. Thanks to this site and Youtube videos, I have already replaced the thermostat and cleaned the throttle body assembly.
