P0308 and P1244 Intermittent

[mechman3]

I am getting these 2 codes together on a semi consistent basis. They are usually accompanied by excess black smoke and a rough idle. I understand that the P0308 is an issue with injector number 8 but what is P1244 and does it affect that injector.

2005 Silverado, AFE cold air, 4" thru exhaust no cat, Stock other than those 2 items 236K miles

Thanks for your help.

P1244 Injector Output Circuit

Need to ck the wiring harness at the FICM it likes to rub through and short out at the top of the mounting bracket where the harness is zip tied to it.

Also ck the wiring and connector over real good at #8.
