Yes, pull all your codes. KOEO, KOER, and cylinder balance test.

Report back with your codes

Thats not a cylinder balance test, but a compression test that shows number two is a little weak

Looks like you need to start from square one and clear all codes to reset computer, do a base idle reset, the rerun your codes

Sounds like a bad ground. Check all your grounds and clean them all up. One loose or corroded ground can wreak havoc on this cars

Not to sound like the grammar nazi, but wtf is it lately with newbs who can't form a sentence or spell? When you do the KOEO test the car needs to be at operating temperature. As Mad said, go back. clear the codes- disconnect the battery for 20 minutes and turn the lights on- then reconnect the battery. Warm the car up then run the tests.

Report back what the results are and be polite and you'll be amazed at the help you will get.
