    Hi folks, Got a 2013 Tundra crew cab. 4.7L. 153Kmiles. I have an engine warning light that comes on for a few hours (or days) but then goes off. No change in performance that I can detect. I had a PO441 a few weeks ago and replaced the PCV and the vapor canister purge valve /solenoid. Also checked the gas cap for a broken seal. Any clues as to what might be going on?

    Did that code go away? Any new codes? Some code readers can read pending codes or the history if the light is off now.

    It's definitely worth the money to just throw your gas cap away and buy a new OEM one.
