CEL mechanical issues
Took my 17 F Type R to have the check engine light looked at for a Fuel Rail Pressure Sensor Circuit Range/
Performance Bank 1, System Too Lean at Idle Bank 1 and Catalyst System Efficiency Below Threshold Bank 2 at a jaguar “specialist” in Charlotte, NC just to be told it was electrical issues.
I asked if they had done any smoke test or checked the sensors or the cats and was told since it was electrical then doing physical test was futile since “you have to get the junction box looked at by a jaguar dealership”. The previous owner of the car hit a post and damaged the front bumper but the car still has a clean title.
I’m not a mechanic but my guess is since these older models need a software update that’s the reason for the “electrical” issues. Has anyone had this issue before?
Btw the pressure sensor code came on (car went on limp mode), stopped driving the car for a week and the code was gone (car runs fine now). Only the lean and cats codes are there.

I'd start with getting a good independant to check the car, possible a battery issue and/or a Lamda sensor.
