Emissions code
So I’ve been having this 2A16 pop up and is preventing me from passing smog. I’ve switched out the gas cap and the leak detection pump. Neither have solved the issue. Took it to a shop to have them smoke test it and can’t find a leak. Could the fuel pump be causing the small emissions leak? Thanks for any input |
