I believe you have to run the XJ threw certain driving cycles in order to clear the code, atleast thats how it was with my 96 XJ( Bored TB, DUI complete ignition upgrade,2000 n up intake w/ APN header, borla catback, summit Hi-flow cat, K&N FIPK).

Sober passenger is definitely a good thing that way they can carry you from the car to the house lol. I just can't beleive the difference the mods have made to the vehicle almost like having a small block in it . Well worth the money$$$$$$$$
