Unpopular opinion: Checking injector spray with a clear bottle beats guessing every time.

My buddy's trick with a soda bottle let me see the pattern and fix a misfire right away.

Hey, solid trick for a basic check. But that clear bottle only shows you if fuel is squirting out, not the actual spray pattern a good injector should have. You need a real pattern tester to see if it's a fine, even mist or a lousy stream. Otherwise you might miss a clogged or dribbling injector that still puts out some fuel. It's a great first step, just not the whole picture.

That bottle trick cost me a weekend once...

Been there, spent a whole Saturday chasing a rough idle because of that. A dribble looked like a spray in a bottle. You're totally right, it's just a quick and dirty check. It'll catch a totally dead one, but a weak pattern will still fool you. A proper tester is the only way to really know what's going on.
