I'm going to go with the ones from Bus Depot. The price is right and I
love supporting our list vendors when I can.

I have to say that the results seemed pretty inconclusive to me because it was really hard to see what was coming out of the injectors and how. I did observe three things, however:

Since I was unsure whether the container I was spraying into was dry to begin with, I dried it out before testing the passenger side injectors and saw the same thing. Blech...
