On my rex i have the normal gsr swap, well i had a good running motor and then hit water, sucked in water and blew out my bottom end. then i got a new bottom end and slapped my head back on. now i have check engine coeds, I have vtec, it runs normally but throws all kinds of codes, 3,7,8,10,13,17,21... i know what they are and have replaced most but still have the code and all wires are correct. what's the deal any ideas?

 

what year gsr was in it and what year did you replace it wit?

 

96 bottom and top end
