i was just wondering if there are anybad habits you guys do when working on your cars. mine is always leaving the wheel lock on the last lug that i tighten and just throw the center cap back on and get freaked the hell out a few days later by some wierd noise coming from my wheel. lol that and i always seem to accidentally set my screwdrivers down on the battery the wrong way, causing the screwdriver to bridge the terminals. so kinda stuff do you guys do (or maybe im just a clumsy pos)
