2014 Viper LTX-SE 240 Hurricane Turbo Kit
I'm having an issue with AFR when not on boost. it will spike to 16 and sometimes even show - on the AEM gauge. I have replaced the O2 sensor and the sensor for the gauge. When on boost it's working properly. I have a 2014 LTX and i've checked the header very quickly and didn't see any cracks. Any suggestions on what to check next. I will pull the header off completely tomorrow and verify no cracks.
 
When your idling, accelerating easy and cruising where your 0 boost, the gauge is reading 16? Or when you snap off the throttle, the gauge spikes to 16 for a split second? Also, pc5 or gems?
 
Pc5 while accelerating easy and cruising.
 
Maybe check out Bad O2 sensor? thread. Could it be the high idle control valve just like Tator? Lets air in if it sticks?
