Why would you be replacing all your oxygen sensors?

As a guess, I bet it is codes P0171 and P0174. AZ read the codes and said the O2's were bad.

Being way2old is why I need help from younger minds

Comment: Here the wires can rust right out of them. Have found wires just hanging - GM truck and just repacled them all but suggest OE ones still. Pre converter ones will send wrong signals and vehile will be brain dead and not run well if at all. Don't wait as a poor running engine for any reason will kill comverters adding to the expense!
