This week just keeps getting better.
Driving to dinner, pulling into gas station to get gas, and I randomly lost power. As in rough idle/drive. Parked it. Checked for codes and got P0351, 53, 55, 57 essentially the entire driver side is not firing.
Checked for fuses. Got new plug wires, all the same. Have not checked for spark but unplugged driver side 1 by one with no difference in idle, all 4 unplugged, zero difference. Swapped coils with a new one I had in the trunk and also no difference.
Have not checked plugs. Waiting on tow truck atm.
Only "recent" mod is a new fuse box. Had it off here in the parking lot and on again, nothing.
Any ideas from you nice gents ?
I'm going to pull the plugs tomorrow, and trace wires I guess. Plugs have like 150 miles on them, and so did the wires, lol.

Bad sub-harness or loose connection to the main harness? I can get you schematics/pinout of the sub-harness tomorrow if needed. I assume you have a multimeter?

 

[mememe123]

Yeah, I have one. Just don't have anything on hand atm.
Schematics will be appreciated 🤘🏻

Well, sure enough, the drivers side head ground is broken off (G136) I hope it's the odd bank ground, either way going to fix it and try to start this thing.

You got started before I did this morning. Here's what I promised, even though you no longer need it.

I think repairing that ground will solve your issue.

Saving for later.
Yeah, lookes like that wire solved the problem. No idea how it has broken off, but it starts/idles/revs just fine now.
Glad I waited 6 hours for tow last night 😭🤣

Too much torque! Ripped it right off.

It was a little crusty. But now it has plenty of slack even thu those wires don't really move much.
