Re: The mystery bolt thread.

You might need to use a afs74 heated o2 and pigtail if it’s not going into closed loop.

Ect 77f or higher and o2 swinging . If o2 is stuck at .450 the o2 is bad or not warm enough.

Re: The mystery bolt thread.

Keep me updated how I can help, seems like it can use more fuel but data will tell the story.
