Oxygen Sensors
I just replace all four oxygens sensor on my 99 Ford F150 But its still runs rough and the check engine light come on.
I get codes P0136,P0141, P0156,P0161,P1131 and P1151 which are the codes for the oxygens sensors.
Any subjestion?

Well, for 0136, 0141, 0156, and 0161, make sure you didn't plug the sensors up backwards. P1131 and 1151, start looking for vacuum leaks. Probably the PCV tube running from the passenger's side valve cover to the rear of the intake leaking. What engine do you have?
