Anonymous, CA (2006 Toyota Tundra SR5 4.7-L V8)""My check engine light came on and the issue turned out to be with the secondary air injection pump system. When the light came on, engine power was significantly reduced. My local mechanic performed the repairs. I have gone to this shop for over 10 years and I trust them to charge me fairly and not pressure me into unnecessary repairs and maintenance. The repairs cost over $2,100.""
