Update:

new o2s seems to have made a difference in the trims.

Now I need to resolve a code 43. I had the code turned off in the tune so I could focus on other issues the engine might have running wise.

Brand new ‘95 knock sensors were installed when I changed the O2s. Suspect it might be a wire issue. Plan on getting the meter out and going through it.

Does anyone have any experience or advice on resolving code 43? I’d rather not put resistors in place of the knock sensors like some people do
