This is the new and improved video on Oxygen sensors. Hopefully you can resolve your issues. Is your "Check Engine Light" on? It may be a bad O2 Sensor. You don't want this to go too long or you'll be spending a ton more in car repairs, namely the Catalytic Converter will burn out, and those aren't cheap. You'll also be wasting gas and have a less efficient vehicle. So get that changed ASAP!
