Oxygen sensors does anyone know where they are located? And how Many? Engine is still idling fast I have changes all plugs because the 1 and 6 cylinders were bypassed and back firing. Then I changed the erg sensor, and still having issue. I am also thinking that the catalytic converter is clogged, so going to take muffler off to see if that helps before buying it.
