I will change those out this weekend. Problem I started with wass going dowm highway if I tried to go over 65 mph engine acted like it was missing. Could plugs and wires possibly fix that?
Champion RN11YCC - spark plugs
This site sells OE parts with competitive pricing
This is the cam sensor picture.
To sum it up: Change the plugs, ignition wires first and air filter. Recommend OE products.
Reset the computer by removing negative cable for 30 sec and reconnect.
Test drive and you will be ok.
Let me know if this help.
Don't forget to rate me excellent please.
Finally got plugs and wires changed. It is better than it was. Codes were cleared and took for a ride again Seems to struggle when I step on the gas hard. Rechecked codes now have p0420 and p0430 any ideas ?

I will try that this weekend working alot of overtime on third shift so dont have a lot of time. Please hang in their with me
Finally got the o-2 sensors in the mail and installed. Also checked for leaks couldnt find any. Just drove it about five miles and everything seemed ok. Turned around and got back on highway. Started stuttering again any speed over 65. Got back home and got Code P1138. Need more help
The next step will be more in depth and require for an automotive diagnostic equipment scan tool made by Snap-On or equivalent. It is a handheld monitor machine that is telling you what exactly all the sensors are doing. This machine is expensive but if can borrow one it will be great.
I am assuming you have changed all the parts that I suggested beside both rear oxygen sensors.
The P1138 was triggered due the oxygen sensors sending over the OE specification values.
Good oxygen sensors voltage should be switching between 0V and 5V under normal closed loop fuelling control. If the sensor is not seen switching, snap open the throttle. The sensor should then be seen to start switching. PASS VALUES: Sensor voltage should switch between 0V and 5V.
Change the front oxygen sensors if the values are over the limit.
Sorry takes so long to get back to you. I took it to a land rover dealer and had it checked. They say the camshaft positon sensor is bad is the only thing that shows up. Need your advice they quoted 840.00 for part.
According to ALLDATA the standard labor rate for cam position sensor replacement is only 1.0 hour MAX.
The part only cost is $410. The part number is NSC100840. Parts.com is 330.29.
The sensor is located Lower Front Of Engine Near Oil Filter.
I changed out the camshaft sensor and cleared code. Test drove today and still have problem. Got home and checked for codes. Got P0340 Camshaft position sensor A Bank 1 Circuit malfunction and 2nd code pending P1138 Any help will be greatly appreciated
P0340- The vehicle's computer is detecting the engine timing is off. The next component to inspect is the flywheel for missing tooth and the crankshaft sensor itself.
The crankshaft position sensor is the most important sensor on the engine. It is located in the left hand side of the flywheel housing and uses a different thickness of spacer for manual and automatic gearboxes. The signal it produces informs the ECM:
I hope you have access to an on board diagnostic computer so you can see what is going on with the oxygen sensors. I don't want to advise you to replace any sensors yet until the P0340 is fixed. The P0340 does have affect on the P1138 code.
Below are the OE reference ranges for the oxygen sensors. If the values are over or under specifications then you have a bad oxygen sensor.
Left Front Oxygen Sensor
Right Front Oxygen Sensor
Left Rear Oxygen Sensor
Right Rear Oxygen Sensor
