I have been dealing with a bad coil(s) issue though so maybe it was just from weak spark that caused it for me. But I had to pull the battery cables over night for it to reset things and run stronger again. This is why I posted a few back that I was surprised GM stated to do this in the procedure you posted because I was under the impression the Bosch ECM didn't need this. I can assure you though mine benefitted from the cable pull over night. I turn the headlights on, pull the cables and let it sit over night.

Fuse pull did the exact same thing for me, but no one will believe me.
Car was sluggish and it brought it back to life, even the rear pipes are clean as a whistle.
