Tonight's two drive cycles at steady cruise freeway speeds makes three in a row without a hint of the rich condition, super lean LTFT. In fact LTFT is at 0.00 exactly now. Better yet, I have not seen the P0420 return, either. This exact drive has set that code off at least 6 or 8 times this month. I wonder if that will continue.
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
