P0031 after resetting PCM :-(
I had a CEL p0037 since i gutted my cat and added a wideband.
But just yesterday i took off my pulley kit and installed my Injen intake and put OEM pulleys back on. I got in my car turned ignition on (not starting car) and press brake 20times rapidly oil pressure sweeped half way.
Well after i did that i noticed my AFR changed to being really rich. before i installed and cleared the PCM my aft wher just right around 15.0 crusiing now there in the 11 and 12's.
why would it do it right after i resetted my PCM.????
can anyone help?
