2012 range rover sport stalling at low speeds. 135k miles.

Customer Question
2012 range rover sport...

2012 range rover sport stalling at low speeds. 135k miles. Replaced mass airflow sensor, still have issue.

Mechanic's Assistant: Is the check engine light on? Does the car stall at idle or when driving?

Both. Code is p2279

Mechanic's Assistant: Are you fixing your Range Rover yourself? What have you tried so far?

I have tried a few things and taking it to a shop. They were able to recreate the stall and look at the codes. Nothing definitive

Welcome, I'm Chris (aka-Moose).

  • THE TIME I AM ONLINE, 7 days a week normally online around midday and then late evening until early morning.
  • PHONE CALLS are automatically offered by the website normally after my first reply. I complete calls where I feel it is a benefit.
  • UPLOADED LINKS I SEND, if I upload dropbox links, they will open on a home PC, often they fail on a work PC, on a phone use the box on the top right of your phone screen for direct download.

My suggestion is to clean the throttle body and check for vacuum leaks (based on your code) a vacuum leak can affect the air fuel ratio and cause an engine to stumble and stall at low rpms.

You now will see a rating scale a row of yellow stars from bad to excellent, because I have posted my 1st full/partial answer. When you rate I get a portion of the deposit you made, no rating means you still paid, but I earn nothing. My goal is understanding your question, and addressing it in full detail. In return, receiving a 5-star rating. Rating does not close the post or stop the conversation. Please keep in contact and reply as much as needed. Thanks, Chris

I have not been able to get to have the throttle body cleaned; however I'm getting the p2279 AND p0087 code now. I'm attaching the output of the OBD tool that i have... wonder if this changes your thinking about the problem?
Auto Mechanic: Chris (aka-Moose), Technician replied 2 months ago

Low fuel pressure can cause 0087 which can also result in a lean code 2279
