So I changed the O2 sensor and my problem is worse. When I press the accelarator it stutters then kicks in strong, if at all. I'm not a mechanic but it also sounds like all the plugs aren't firing. Getting a full tune up, but if that doesn't help, anymore leads?
Also I tried to get the codes and have no idea how switch modes. Mine does not have the "screw" that locks in the mode, or if it does I can't find it?
