I have the same exact car and having the same problem. how did you order the charcoal canister? I went to lexus-parts.com and called them up and they want to charge 288.79 + shipping. After the asked for the VIN number, they told me that the charcoal canister is sold by itself for the above cost. Did you buy the VSV and the charcoal canister or just the charcoal canister? Thank you for any assistant.
