persistent codes P1128 P1130 help ..

[stateofidleness]

Vacuum leak? I had these two codes off and on forever... dug into an AOS replacement recently and found one of the brittle hard plastic vacuum lines to the changeover valve completely broke off and just laying there. It's hard to see because it's sorta underneath the passenger side intake manifold.



Worth looking at all your vacuum hoses, and the evap canister as well.
