i have a 2013 Jaguar XF 3.0 supercharged,base model. About a few months back
I’ve had some really bad injectors,fuel was beings dump in the oil and the tail pipe.
about a mouth and a half ago I had to send off my injectors to get clean at a place in Huston that had the GDI machine and equipment to do so , there was no place here in Oklahoma , I was unable to buy new injectors because of Bosch had the injectors on back order for 2months. I did all my work my self and the car has ran really great. This morning the check engine light came on, and I read the codes with my own scanner , it has jaguar capabilities.
I also know the P0420 code can mean multiple
such as o2 sensor,exhaust leaks,
plugs,air filters and injectors.
when I put my injectors back in i also did 2 oil change with Bg products back to back that night and put new plugs back in as well.
so my question how to trouble shoot this code?
what would the odds be of injectors problems again?
and just any advice will be appreciate
Im going to try to attach the injectors report, when I sent them off.
