I recently got both cat converters replaced and now I'm getting a P0141 code.
It doesn't come on at first...but after I drive it, stop and start it up again then it comes on.
This leads me to believe that it's not a wiring or instrument issue but possibly a lean mixure due to a clogged fuel/air filter...dirty injector ports...ethanol fuel..
Perhaps also different exhaust components may change aspiration characteristics enough (3 of 5 exhaust components are aftermarket).
What do you guys think?
I'm concerned because they may not inspect it with that code there....
