The Carbon monoxide was way too high, so I took it to an import specialist and he's saying that I need a new fuel injector pump. It's not the fuel pump, but the injector pump.
The mechanic said that these are not very adjustable and I need a new one - which he said costs around $1600. Yikes! Does anyone know any tricks to adjust these so I don't have to buy a new one? Or maybe the problem with the emissions is somewhere else?
