P0101 Jaguar -

Question

I have this code that shows up every 100 to 150 miles then resets it self. The dealer change air filter and said that should take care of it.
After about driving for another 150 miles check engine light comes back on and dealer tells me it is the same code after I return car.
So they decided to swap it with the left side to see if the problems change with the sensor.
After driving about another 150 miles light is back on and dealer tells me the problem stayed on the right side, it did not change with sensor.
Now they tell me it probably going to be a injector issue.
The problem I have is I have not really notice any difference in engine performance.
Any help would be greatly appreciated.
