Well.....................
I pulled the heat shield off the exhaust manifold to get to and have a better look at the task at hand and all that is needed to change the O2 sensor. The engine light is on in no small part to the crack in the manifold just above the O2 sensor fitting. I fail to see any point in installing the new one I picked up this week as it is bound to "light" up again. Honda has extended the warranty coverage on this problem so I'll be on the phone monday morning. What a kick in the teeth. I am unable to have the crack welded as it runs directly into the threads for the O2 sensor. Is this a job for JB Weld? I don't think so! If Honda tells me to pound salt I'll have to start looking for a used manifold or perhaps the aftermarket? This really blows, or leaks? I think I need a drink.
