A few months back I had to replace my evap canister because I was told by my console display to check the gas cap. It fixed the problem. Now today when I went to work and started cruising my cel came on and threw that code at me. I erased it and started my car again, came on instantly. The first time I did this a few months back when i replaced my canister it took a few days to come on because the system was not "on" yet, but this time was instantly.
What should I replace? or look into fixing?
