I recently did the ZZP header/dp install. I am aware that there should be a P420 code being thrown but its not one of them. Several of them are related to O2 sensors though. Anyone know where I should start to look around? The O2 sensors are seated well and connected fine. In addition to these codes, my cruise control only works for about 0.5seconds, which I assume is also related to the O2 sensor.
The list, all P00xx
P0443 Evaporative Emission (EVAP) Purge Solenoid Control Circuit ECM, PCM
P0141 HO2S Heater Performance Sensor 2 ECM, PCM
P0135 HO2S Heater Performance Sensor 1 ECM, PCM
P0102 Mass Air Flow (MAF) Sensor Circuit Low Frequency ECM, PCM
P0036 HO2S Heater Control Circuit Sensor 2 ECM, PCM
P0030 HO2S Heater Control Circuit Sensor 1 ECM, PCM

 

check for pinched, disconnected, or melted wires around the exhaust

 

I couldn't get a good look of the wiring from below when I was doing the install, but it looks like both sensors are failing? Are the wires from each running together to a common location?
