I guess changing the gas cap is my next step. I found this on amazon (
Amazon.com: Stant 10843 Fuel Cap: Automotive ) Does anyone knows if I got the correct one? Thanks.
Same thing happened on me. First the blinking light once a few weeks, then once a few days, then the P0455 code. Now both blinking light and P0455(after I reset) came on everyday.
Where are the vacuum lines located? or do I just inspect all the black rubber hose under the hood?
No, I stop at the clicks, although I might have did it a long time ago.
