P0420

My 2011 Honda CR-V has 82,000 miles on it. The check engine light came on six months ago. As the weather warmed up the light turned off and the car passed the emissions test during annual inspection.

Recently, with the weather turning colder, the light returned, and it has stayed on. I bought one of these for $17:

The OBD II scanner reported this:

P0420 $f111
Catalyst System Efficiency
Below Threshold Bank 1

So, it would seem the catalytic converter is failing. I reset the code to turn off the check engine light, but it’s certain to return.

I bought the CR-V new, fifteen years ago this coming May. In Massachusetts, a 15-year-old car is exempt from emissions tests. What to do… what to do…

Wall St. Week recently featured the medical information startup OpenEvidence.

If this outfit goes public, it will be the first time I buy stock in a company other than my former employer, which is privately held.

Biggles for the Ages. Here’s Why.

I am so sick and tired of “Here’s Why” being tacked on to every frickin’ headline. I hope its use is fading.

The name “Biggles” was used for laughs numerous times by Monty Python. I’d always thought Biggles was just a silly Python name, but it was a long running series of stories and books in England. There was a Biggles TV series in 1960.

This 1986 movie adaptation, Biggles: Adventures in Time (the American title), was recommended to me. It’s Peter Cushing’s final screen appearance. I haven’t watched it yet.

P.S. Definitely worth a viewing! Lotsa silly fun, and some very impressive war scenes, both on the ground and especially in the air.
