hey guys. gotta b18c with usdm p72 ecu. when i first got the swap done, i had the knock sensor code, drove around for almost a year before i got the thing replaced (spark plugs looked fine for a few months then they really started to burn out). after i finally got it fixed, i threw the O2 sensor code. i just replaced that along with my cat this past weekend. now the stupid knock sensor code is reappearing! WTF! (both parts are OEM Honda/Acura parts).

has anyone seen this? and yes i've tried clearing the code twice. possible bad ecu? i don't want to drive around with the code the way i did before. all help is appreciated. thanks.
