Just recently replaced the exhaust gasket and bank 1 02 sensor before that. I already know I need the bank 2 sensor but why is my truck riding rough after the gasket repair? while it is in gear, it is fine, but when I first hit the gas to accelerate, it hesitates for a second, then rides normally. why?



already had oil change, tuneup, fuel pump changed.
 
Did you use the right gasket sealant? some 02 sensors will "smell" the adhesive and adjust the computer based on that. If you did use the right sealant, I would replace the other sensor.
