There is no 'ping' when it misses.

What does the K40 relay control?

Yesterday was the first that I had noticed it. Monday I filled up at a different place than where I currently buy fuel, however, it is the same place where I used to buy fuel.
In that case I suspect bad fuel or a fuel leak somewhere as I mentioned last time. Did you check under the black plastic cover? See if there's fuel puddling in one of the injector holes. Also try adding some cetane booster and water disperser if you suspect your fuel is bad.
