99 Disco II 4.0
I have replaced the O2 sensors, the MAF, the air Filter, the plugs(bosch4), the wires(magnacore), ran seafoam through the intake and through the gas tank and keep getting the same codes.
first I get these
P0135 Front sensor heater LH bank - short/open circuit
P0155 Front sensor heater RH bank - short/open circuit
P0134 Front sensor LH bank open circuit
then later it will stumble badly and I get these
P1300 Catalyst damaging level of misfire on more than one cylinder
P0303 Injector 3 excess emissions/catalyst damaging level of misfire
P0305 Injector 5 excess emissions/catalyst damaging level of misfire
P0307 Injector 7 excess emissions/catalyst damaging level of misfire
P0301 Injector 1 excess emissions/catalyst damaging level of misfire
P0300 Excess emissions detected on more than one cylinder
Since it's only on one side I assume the gas and filter are not the problem.
Is the LH bank the drivers side(USA), cylinders 1,3,5,7?
If so could the O2 sensors be causing it to mess with the fuel/air mix so bad that it would missfire?
My plan this evening is to swap the O2 sensors to opposite sides and see if I get RH bank errors, does this sound like an O.K. plan?
