That's a typical coil low grade misfire. A characteristic after KAM Clear/ battery reconnection.
It's coil or compression. Injector, -it's possible, but very doubtful IMO.
Since it's getting worse, try to identify the cylinder. DON'T RESET the KAM.
Bring the Misfire count up thru Drive Cycle. Go for a ride, give it hell when it's at it's worst. Right after the shift into OD under normal excel, then nail it! Do what you have to keep it missing until you get a blinking CEL. It will blink 4-6 times then shut off, watch for, check for DTC's even when CEL is off. Keep your scanner plugged in during drive cycle if you want.
