I have a 05 xlt 4.0 with a little over 145,000 miles and within the past few days it developed a rough idle. This morning the service engine soon light came on and I took it to Mr.Tire to have them get the code. They got code p2195 for an O2 sensor stuck lean. Bank 1 sensor 1. Any ideas on how to fix this?

Also I just replaced the harmonic balancer this past weekend, but I don't think that would have anything to do with it. Would it?
