Hello,

Just want to update you all on my sister's car which had the Service Engine Soon Light and misfire with the following codes P0130, P0171, P1171. After searching online for what the codes ment I found the following 2 sites;

I also talked to a Land Rover Service Rep and I finally ended up changing the front Pass. side O2 Sensor and that corrected all the problem, so I hope this helps you guys.

 

I have the exact same codes. I guess i'll start with the front passenger 02 sensor. How did you know which sensor to change?
