Hi all it’s been a while since I’ve been here, mostly because my car has been running relatively well…until recently…
my car started running really rich on bank 2 to the point I can smell/see fuel coming out of my tailpipe…thankfully I have AEM Infinity so I can monitor what’s going on (I have a CJM return system with FPR). Fuel pressure seems consistent so I think the FPR is ok…my AFR on bank 1 is at the normal ~13-14 at idle but on bank 2 it runs in the 9’s…and I can smell gas…
There are 2 likely causes here, I’m thinking it’s probably an injector stuck open or overflowing on bank 2, or maybe the o2 sensor on bank 2 is shot.
It’s probably the injectors so I’ll probably take the injectors out and send them to ID for a clean/repair, but I wanted to see what you guys think, if it could be the O2 sensor, or maybe even something else I’m missing…thoughts?
