Here is whats recently been replaced:
Passenger front and rear 02's.
Spark plugs (E3 Spark Plugs E3.48 Automotive, Truck, Van and SUV OEM Replacement Spark Plug , Pack of 1 AMAZON)
Waiting on spark pug wires.
CODE ISSUES:
P0130: O2 Sensor Circuit Malfunction (Bank 1 Sensor 1)
P0300:Random/Multiple Cylinder Misfire Detected (Obviously because multiple misfires)
P0301:Cylinder 1 Misfire Detected
P0161:O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2)
P0305:Cylinder 5 Misfire Detected
P0307:Cylinder 7 Misfire Detected
P1300:Boost Calibration Fault (I don't understand this one)
Every once in a while I get these:
P0134 O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)
P1129 Downstream Heated O2 Sensors Swapped
P0171 Fuel Trim System Lean (Bank 1)
P0160 O2 Sensor Circuit No Activity Detected (Bank 2 Sensor 2)


What does everyone think? I will replace the plug wires when they arrive. I think the coil might be going bad but cylinder 3 isn't having any issues.

 

have you tried reset any of these codes after installing the new O2 sensors?

 

Been down this road , trust me on this use only landrover 02 sensors ,if not u will have a rough ideal . And do the two of them .

 

Install your new 02's, plugs and wires, then clear the codes and let us know what shows up still, if anything. You are on the right track.

 

I have reset the codes with the ultra gauge.
I did, I ordered them from atlantic british.
Any advice on how to get the drivers o2 before the cat out? I have tried the special socket, penetrating oil, tapping with hammer.. It just won't budge. I have heard using a blow torch to heat up the pipe can help.
Thank you all for your time.

 

Definitely try torching the pipe, it'll expand the metal and make it easier. Also, the longer the handle on the socket you use, the more torque you're using.

 

It looks like all of your misfires are on the "odd" bank. I'll bet replacing your o2 sensors helps that.

 

I don't remember which side it was, but one of my front o2 sensors on my 03 was so covered in oil that it came out with no effort at all. How long did you let the penetrating oil set to try to work?

 

Thats why I was using a 32 inch breaker bar! I was torquing it hard and didn't want to snap something.
Correct, but doesn't it seem odd I'm not getting a cylinder 3 misfire too? If I was then I would think coil.

 

you can try heat but that connection has already been heated and cooled a million times just buy the converter exhaust.
I would soak it in SeaFoam Deep Keep and put i big *** box wrench on it or make a full commitment and cut the wires off and use a socket and breaker bar.
Also just because you bought the 02 sensors from Atlantic British does not meen they will work. There are a few old post from people who went thru two or three sets of AB 02sensors before getting there money back, there is a reason they are only 69.00.
