I got a PO451. Where should I look for problems? I know it's the evap pressure / performance out of range. Any good place to start? Here is the data:fuel sys 1 -cl:calc load-22.75:ect-190:stft b1-.78:ltft b1- -1.56:map-10.63:rpm-1128:veh speed-34: also a PO455 was found

I would have the syetem fogged. What they will do is force fog into the EVAP system. If there is a leak, the fog will come out and the leak will be identified.

That is how I would start. If you try to find a leak, you'll look forever and most likely not find it. They are a pain.
