I finally listened to my buddy about using a proper torque wrench on injector lines instead of going by feel.

For the longest time, I'd just tighten them until they 'felt' right on my old 7.3 Powerstroke. My friend, who works on semis, kept telling me to get a torque wrench and follow the spec. I finally borrowed his 1/2-inch click-type and did it right on my last oil change. The difference in how it idles now is night and day, no more of that slight miss. It was a $40 tool I should have bought a decade ago. What's one simple tool or step you all put off that actually made a huge difference once you started using it?

Read a forum post about using a torque wrench on spark plugs, same deal. What took you so long to try it?

Yeah that "what took you so long" bit is real. I saw a whole thread where a guy stripped his plug threads because he just cranked them down by feel. The repair cost was crazy compared to just getting a cheap torque wrench. It's one of those things that seems like overkill until you mess up one time. Now I torque everything I can, because that one mistake changes your mind fast.
