yea i cant just park it tho, need to get around, i just dont rough house it right now. but ka, what scanner do i need, and what should i be checking for?

and as a curiosity i wanna change the pcm.. anyone kno what years/models will fit? cause i can get a pcm from a 99 supercharged buick, wondering if thats the same or not..!! ?
Im gonna try locate a borescope and check out the pistons make sure they are not damaged aswell!
