Hello,

I'm new here and you all come highly recommended from other Jaguar owners I've talked to. I've got a bit of a strange one I'm wondering if anyone has run into before I have to take the car in and bite the bullet on that invoice.

It's a 2016 XF R-Sport 3.0L Supercharged.

It is running rough at Idle and I'm pulling the code "System too lean at idle"

I have now replaced both MAF sensors thinking those were the problem. The strange thing is, when I unplug one of the MAF sensors the idle completely smooths out. I'm wondering if I maybe got a bad sensor out of the box. But if anyone else has run into this I'd love to learn what you've found.

Thanks!

 

The throttle body needs cleaning. Spray the butterfly with carb cleaner and see if the idle improves
