Alright, so I got a replacement O2 from innovate and it worked great for about 2-3 days, then BAM, started messing up again. After driving for about 10-15 minutes the LED starts blinking, but it isn't error code blinks it is just sporadic blinks then it will go solid. Then it might wait a little bit and go solid again. Sometimes I have even had it do a heater calibration in the middle of driving, which brings me to my question. Where do most of you guys run your heater power and ground if you are NOT doing NB simulation? I currently have it tied into one of my stock O2's power and ground. Any ideas?
