Ran Out of time and didn't feel like dropping the drive shaft so I only replaced the passanger side. Drove the car about 20 miles and. My check engine light came on, anyone think that maybe the o2 sensors were on there way out computer was compensating for two bad sensor and when I replaced the one it triggered to the computer that there was one not reading correctly because I put in a brand new one. Truck has 144k looked to be stock sensors, and even though the light check engine light is on the car is running great

Just get the code read. The read out will tell you which bank and sensor, no guessing about it.
