That one was worthy of sharing the top of the list, so I edited the post.

Wow, I could spend hours on this. In a nutshell. The STFT maintains everything as close to 0% as possible. The LTFT learns from the STFT. Both are logged by the ECM.
Either a rich/lean bank condition affects the 02 Sensors input to the ECM or vice-versa (Bad 02) causing the opposite effect by commanding the injectors pulse with for that bank. Then there is up-steam and down-stream systems, Wide / Narrow Open / Closed Loop, band systems, and older generations such as the 1980's GM's and such.
There is a guy on you tube named scanner danner. He explains it pretty well. I bought his book because of his graphics, primarily of the Scope Snap-Shots so I could use them teaching.
I've communicated with him several times and he is a teacher at a Tech School and does his own business like I do contracting with Dealerships and Shops In the Area. Great Guy!

Don't start a job without planning ahead. Think of all the little jobs the big job may encompass, and you'll save yourself a lot of aggravation.
Don't forget to clean whatever it is you're working on. While it's out, and everything that comes out with it is out, take the time to thoroughly clean it and inspect it before it goes back in.

Don't forget to disconnect the GPR before cycling the ignition many times to test the installation of a stereo, door lock actuators, gauges, etc. Glow plugs kill the batteries if you ignore this advice.
If you park your truck for a month between drives, don't forget to install a maintenance charger on the batteries and plug in the truck 24x7

Unfortunately I have a couple to add:
Don't replace the rear o-ring on the HPOP without using the recommended C clamp.
If you wonder how much crud has accumulated in your heater core and you remove the access cover, don't accidentally puncture a hole in the heater core when reinstalling the screws into the cover

When you know something is wrong with your truck and ambition (or lack thereof) is the only thing in the way of resolving the problem, don't permit procrastination to be your passenger. An intermittent problem can go permanent in an intersection. Right, Pop?

It is a hard pill for me to swallow since I am so good at procrastinating.
I would be a member of NPS (National Procrastination Society) but I keep putting it off.
I must have missed something about PoP ???

SpringerPop had intermittent stalling problems for months, and he waited until he was permanently stalled in an intersection to take the CPS out of his glove box and put a wrench to it. It could have been any one of us, so I shalt not cast stones frometh my glass hut.

Let me just add on to the PCM one, don't install or remove a tuner or chip with the keys in the ignition. You will fry your PCM. Throw those keys as far as you can away from the truck.

Who do you think formed the NPS? It took years, but I finally asked somebody to do it for me.
SpringerPop had intermittent stalling problems for months, and he waited until he was permanently stalled in an intersection to take the CPS out of his glove box and put a wrench to it. It could have been any one of us, so I shalt not cast stones frometh my glass hut.

But all kidding aside it does make me feel better knowing I am not alone on the whole procrastinating thing.
I think Pop's story should be something we all learn from at least realize that could have been or will be one of us dead in the middle of the road.
Pop I hope that cut on your head doesn't leave a scar because that could be the end of your modeling career !

Don't get pissed off at your truck for slapping you in the back of the head reminding you AGAIN that you are a member of the NPS club 
and it wants new hood struts! And don't retaliate by pushing the hood open harder and further. When you close the hood the FIRST thing through your mind is Tugly's Don't do the doo thread 
It tends to alter the hood and fender body line. A block of wood and down pressure and the body line is good again, starting to shop for struts!! 
Well maybe when I get caught up reading on the threads.
