Does anyone know of a reason that my O2 sensors are not "cycling" at idle on my SD tune>> :*****:
I have a 98 that has a 02 PCM. at idle (up to around 1400 rpm) the O2s stay in the 900s and the AFR is in the 12s. If I rev it up to around 1400 in gear, the O2s cycle perfectly and the AFR is close (VE needs tweaking)
I purchased new O2s and it didn't help, so the original ones are actually in it right now
I have been fighting this issue for around a month, :crazy: but a crazy work schedule, the holidays and consistent rain every weekend has hampered any testing. I'm ready to get this thing back on the road:yesnod:
