I have dps, fmic, dcis, chargepipe, and exhaust. I have been running mhd stage 2+ for the last two years. I have been getting some consistent misfires lately. I decided to change my injectors with index 12s and replace the rear O2 sensors (due to consistent rear O2 sensor codes). I just started the car and it stumbled for a couple seconds and then it was fine. I let it warm up and took it for a drive and the afr is stuck at 14.68. it doesn't change at all. At cruising speed and idle all seems fine. I tried to get into boost and it stumbled very hard. No codes. Any ideas?

Do you have a log you can post? The rear o2s can influence AFRs but not to the degree I would expect the afr being stuck there.

If you are not WOT, just cruise, then it should target 14.68, but a log would definitely help.

Im too nervous to get into it. I can log it at cruising if that's what you're asking. The lp and hp fuel pressure look good. Everything else seems fine. The only thing I did was swap the injectors and code them. Then I swapped the rear o2s. I did reset the adaptations. Could that have messed something up?

This happened to me once, it was an all-of-the-sudden thing, I reflashed the map and all was well. Never did figure out what happened.

Interesting. I will try a reflash. Do I have to flash to stock first? Or can I just reflash the stage 2 map?

I flashed the MHD stage 2+ map again and it worked. Everything seems fine now. I took it for a quick ride and it hit boost and spun the tires in third (perfect!!), Haha. Chris, thanks for the quick reply.
