    Hi; I'm From San Juan Puerto Rico. I have a v6 Tundra with 115 thousand miles. recently lost power and it is difficult to pass 2000rpm on the street. the check engine turned one and changed the two oxygen sensor. It was scanned again and has no codes. What could be?

    With the engine running, remove the fuel pump fuse (under the hood) and let the engine run until it stops, otherwise when you release the pressure at the filter gasoline will spray everywhere.

    FWIW, I missed this handy trick when I did mine and didn't get completely soaked in fuel. I cracked the lines and let it bleed out on the rags under it. Does it have any misfire codes?

    Check your TB for misaligned throttle cable. That could be your issue. Transmission stuck in first gear maybe?
