Hi guys so my issue is i noticed that my truck is runinng rich on idle and crusing etc except the full throttle because i have a tune , so i checked the readings for the o2 sensors and i found that the passenger side is not working or when i put the diablo perf or the stock tune is waaay off so i replaced it nothing changes !! I'm really worried that it's going to be a huge problem my truck is a 2014 ram 1500 8speed

i would remove the tune and let the dealer check it out.
