Hello, new to the forum. Having an issue and kind find any info on it... today I lost all power while driving. I found that there was a secondary ground wire to the battery not properly connected and was sparking when I popped the hood. I got it back right and I still had a check engine light and power light flickering. The truck now won’t get past 4th gear and shifts rough. I double checked the ground and checked a couple fuses. Can’t really figure it out and can’t find anything in a gas truck online. It’s a 2012 2500 5.7. Any info is appreciated!
