I recently had a complete valve job done on both my cylinder heads to clear up a missfire code. Once I got it back from the shop, The SES light came back on with a P1416 AIR system fault code. All the vaccumm lines look fine to me, so I think it might be the AIR pump gone bad.
How do I know for sure? Thanks in advance.
