Default multiple engine codes

97 coupe.

I am fighting with some type of gremlin. Have had it happen a couple times now.Multiple engine codes and check engine light comes on.I have 7 codes.I am certain that it is a grounding issue but wonder if this would cause my HAVC to come on erratically?

she is all stock(put a Z06 air box in).43000 miles

getting that many codes in one go cant be normal?

it all started with the reduced engine power warning,i cleaned a bunch of corrosion under the battery and all was good for a few weeks,now i have got the check engine light 3 times.
just dont want to change parts if I dont need to.

carpet is dry.

do you think the B0432 H could have something to do with the HAVC controls taking a minute or so to come on?sometimes it comes on right away other times SLOW
