I have a 2003 FBO(Full bolt on) with Kpro V4, I took it out for a drive last week and I had a P0139 CEL, this happens intermediary. This happend shortly after I disabled the ELD via krpo. Could disabling the ELD cause this code to pop up?? I've checked all my wires and PCM and couldn't find anything that would draw extra voltage. But any help would help.
