I’m new here so hey you guys! I have a 2011 Buick Enclave cxl it was having some issues with going uphill studdering and then one day it stopped running and when I popped the hood the catalyctic convertor was glowing orange it scares me! But long story short I had a mechanic look it and he said the timing was off so we put it in the shop and then we decided (from what the mechanic said) to do a motor rebuild costed $3600!! Needless to say I got my truck back 7 months LATER and it still doesn’t run and it’s throwing some codes that say ignition coil circuit high it has three of those codes. The mechanic told me not to crank the truck until I had the electrical fixed but that he couldn’t do it I’m broke after paying him does anyone have a wiring diagram for the ignition coils? And also does anyone have any advice or pointers I’m just a single mom trying to survive and I’ve been without a ride for a long time! Any help would be appreciated!!! Thanks!
