Running terrible after trans install.
Running terrible after trans install. Hey guys, having a problem with my car after transmission replacement. I broke the input shaft at the track, engine hit the rev limiter when it broke. The trans shop removed the front o2 sensors during repair. The rear o2's are deleted the are some sort of
Now the car runs very poorly at cruise-light throttle after it warms up it gets worse. The air fuel ratio swings from very lean to very rich. Car runs great at wot. The only dtc it was showing said Maf performance error (immature) (pending)
I'm not sure if my config file attached correctly, if not how do you get it into a format that will work? Thanks,Brian

Did you put bigger injectors in it and not tune for them? There are times your STFTs are pulling 60-70% of fuel while cruising. You might want to check your fuel pressure and make sure it is not abnormally high.
No didn't change anything, Car was running fine before the trans broke. Tranny shop said they tipped the engine back to get at the bolts. I'm wondering if maybe the map sensor or intake might have gotten cracked?
I tried to spray some carb cleaner around the intake but cant really get into the back area to try there.
I'll see if I can check the fuel pressure, thanks.
