Hey all, as title states, I'm having issues with my entire bank 1 coils. I started her up for the first time in a few months today, and my wideband gauge was showing an off the chart lean reading. Pulled codes and cylinder 1,3,5, and 7 coil packs were not firing. Has anyone else encountered this issue before? If so, what was done to fix it?" I'm assuming it's a bad ground somewhere, but I'm not sure how the coils are grounded (individually or all together or separated by banks). Any input helps!
