P0455 is an EVAP system leak. The things you did are unrelated to this code.

I just got my car back today from the mechanic and now I have this issue. Is there any way possible that something could of been done with out them realizing that they did anything

Car drives fine, no gasoline smell or anything else weird going on with it.


You will probably need to do a smoke test on the EVAP system to find the leak.

Won't be able to do anything till Monday when my mechanic is open. Will the car be safe to drive until then?


You must judge that but I think you are good.
