2007 tundra 4.7 has no engine power. Revs out but hardly any get up and go. I replaced both secondary air check valves. Replaced the secondary air pump (4.7 only has one). When i clear the code p2445, the engine regains its power. After it sits for a bit, the code reappears and the engine losses its power again. Every time i clear the code, power returns. Any suggestions??? Thanks

Sounds like the truck is going back into limp mode every time the code pops back up. If that code is for the initial problem, it sounds like you didn’t get it fixed right or everything plugged back in properly.
