I got a 08 4runner 4x4. its at 66k miles. been getting this cel po418 for Secondary Air Injection System Relay A Malfunction? the first time it came on was after i changed the oil, im pretty sure it has nothing to do with changing the oil. so i popped out with my scanner and cleared it and it didn't go away. after the 3rd time it finally went away. now after 1k miles, it came back, cleared it the first time and it went away again. Im just thinking that after another 1k its going to come back and its obvious i have a problem somewhere. I just dont know where or what this is. can someone shine some light in please. TIA.
anyone know how to fix PO418 or what it means?

Is this a 1GR-FE or 2UZ-FE? The 2UZ-FE's had some secondary air issues mostly in the Tundras, but sometimes in the LC, GX470, & 4Runner platforms.

Judging from his previous post, it's a V8
