Codes P1457 and P1456?

Could very well be the problem. The system would see that a solenoid had been triggered when it shouldn't be. Hope to hear good news.

I finally got to test drive my car long distance with a few drive cycles. The light stayed off for about 800 miles and finally came back on for P1457. It usually came on at 300 so there is some progress. I am not sure what else to check. :( The only component that hasn't been replaced with a brand new part (only used) is the canister purge valve. I did replace the hoses but had put the original hoses back in a while back. Maybe I can swap those back with the replacement non hoses. I had to use gas line hoses since the oem ones were discontinued.
