I had CEL code #15 on a hybrid ecu (95 vr4), which is for isc, so I bought a new one on dsmisc.com but still getting the same code. It seems to be functioning fine, but haven't had a chance to drive much, before I knew it wasn't behaving perfectly because occasionally the car would stall when I was shifting, or when slowing down the rpms would dip really low almost stalling (ocasionally actually stalling) then go back up to normal. I've been searching/reading and somewhere somebody posted that the downpipe o2 sensors can also cause CEL Code 15. Can anyone confirm this? I don't think that's my problem cuz I had the stalling issue mentioned above before replacing isc, but want to know if that's a possibility. __________________ 1991 Red JDM Mitsubishi GTO SR - Daily Driver Dec 2001 - May 2002.
