MAF sensor ?
Can a dirty MAF cause the raedings from the O2 sensors to go lean.
I just bought a used one and everything seems to work fine except sometimes when sitting at idle my AFR will go way lean on the wideband and during this time my scanner is showing both my O2 readings staying around 40mv. This only lasts for a few seconds then the O2 readings start moving again and my AFR goes back down to 14.7.
