1999 SC300 EVAP issue
I changed my spark plugs a few months back. Ever since then I have gotten code P0446 (and P0171). This appears to be an issue with the EVAP system. It might be a bad charcoal canister solenoid. Sometimes the car takes a few cranks to get it started, otherwise it runs fine. When I was reassemblling the upper intake manifold I MAY have confused this vacuum line which just so happens to be the EVAP line (line with green cap). There is a solenoid nearby (blue wire plug)with NO lines attached. Can someone confirm this is correct inthe photo of the rear of the intake manifold?
Thank you,
Dennis

After an hour or two of googling I may have figured this out. It looks like I am missing a small U-shaped vacuum line that goes from the port currently used by the EVAP line in the photo and to the bottom of the blue-plug solenoid port. The EVAP line might need to be moved to the top solenoid port.
