The last part under "Caution" means that it won't reset without using an actual OBD scanner, and clearing the self learning of the ECU. Sometimes, with hard codes, you can turn the light off by disconnecting the battery, but the ECU needs an actual reset to start thinking right again.
Great info sir, I really appreciate it! That is the funny thing is that the CEL turned off before I got in the car the next morning! It did reset on its own without the scanner! It did store the code in my ECU when I did go to Autozone though, but the CEL was not there. I did disconnect the battery when I took my intake off though yesterday to reset the ECU per codys guidance, and it seems to get a little better as I drive it. Do you know about how long on average the ECU takes to re-learn or what-not? I have put roughly 80 miles on it since yesterday on purpose to see if it would do that. Like I said it seems to get better as I keep driving it and definately no CEL has came back. And on the info you gave, I have had bad idling and poor driving performance but never problems with starting. Thanks Cory!
