front 02's dead
front 02's dead Ok, here's the deal. I've ran open loop for quite a while and now want to go back closed loop. CL was disabled by raising the ect to max.
I've installed brand new O2's, and put the ect temps back to normal. The O2's just sit there dead though. I checked the wiring to the pcm, checked the 12v, and checked the ground. ALL check good. No shorts, no opens, ALL GOOD.
Even when I force the car into closed loop with HPtuners, the front O2's just sit there dead.
At idle I was right at about 15:1 according to my wideband with no o2 activity. Both O2's are sitting at .854 mv. WTF am I forgetting????
