    Code reader or scanned and diagnosed? What parts? What tests performed to verify cause of problem(code is meant as a guide)?

    Code reader keeps giving me a P0449 code, which is a EVAP emissions control system valve/solenoid. I recently took apart and cleaned the part, which had a dirty filter and dirt in the canister. Cleaned it out and reinstalled it. Maybe a bad part? The trailblazer is still throwing up a check engine light. I also disconnected the battery and both pcm fuses to reset the system and it took the check engine light off and then reappeared. So I let it idle for 10 mins and drove it around a couple blocks and parked it again. Sounded good on the drive and no reduced power mode. Any more advice?We also replaced the AMF,throttlebody,pedal sensor,fuses,cleaned fuel injectors

    A professional scanner that can perform an evap system 'function' test , would be ideal for your situation.
