Ok, here are the code defs.
P0172 System too Rich (Bank 1)
P0302 Cylinder 2 Misfire Detected
P1380 EBTCM DTC Detected-Rough Data Unusable.
So, with the #2 cylinder misfiring I would suggest swapping one plug wire for another and if the misfire moves to the cylinder you swapped with then I would say you have a bad wire and would change wires again. You could also check with the parts store if you have the receipt and see if they have a warrantee.
And if that wire is bad that can be causing the code P0172.
I will need to check on the code P1380 because that reffers to the Transmission Control Module and they are usually only used on Automatic trannies.
