Bump

 

Put a working iacv on it, this will get it to idle correct. No sense in deleting this part, never understood why people do this (not the same as removing coolant lines). As for deleting the knock code, make sure your hondata is functioning correct, you should simply have to disable the knock sensor under whatever parameter it’s located and then upload the new setting. Post a screenshot maybe.

 

Try checking your tps sensor with ohmmeter.
