Hey all so I’m doing some work for a buddy, and I changed out his bank one position 1 o2 sensor. Well now that it’s back together we are getting a code for ignition coil primary and secondary fault for coil c. I don’t remember the exact number sorry. I’ve tried swapping coils around to see if it’s the actual coil but it isn’t. This leads me to thing wiring because the plug is good too. I just don’t know where to start. Like how do I make sure that it’s getting signal, power, and ground. I’ve double checked all the wiring for the o2 sensor. I did have to drop the exhaust to finally get to the o2 sensor after having broke about 3 crows feet. I’m not getting any exhaust leaks either. I’m just stumped and have no clue on where to go from here. Thanks guys!
Also we haven’t driven it because the misfire sounds super bad. I don’t know if that help at all.
