    Default Random Lean Condition

    I've had my Sniper installed for about 15 months and have had mostly positive experiences with it. Roughly 1200 miles on the Bronco since install. About six months ago, I started to get some random high AFR readings. These readings were in all driving conditions and even at idle. It was also doing it with Learning disabled. I assumed it was a bad sensor, so replaced it and that seemed to fix the problem, until today. It started doing it again. These high readings are random and not consistent. It should also be noted that I can not tell a difference in the way the Bronco is running when this is happening. Could it be two bad sensors that take about six months to fail? Anything else I can look for? I have a datalog and can email that. I have yet to contact Holley as I thought I would start here first. Thanks.
