Car starts but runs rough and is in limp home mode and requires a tow. The problem I believe is the throttle position sensor plus supercharger bearings that are on their way out.The car has 96k miles I just got another car and don’t have room for it this is the rare super V8 version of the Xj meaning it has the LWB and luxury features of the Vanden Plas and the supercharged engine of the XJR. *The car has UPDATED TIMING CHAINS AND RAMPS ALL OF IT NOT JUST SECONDARY TIMING EVERYTHING TIMING RELATED WAS DONE RECENTLY And has a rebuilt abs module Comes with some extra spare parts (coils,more interior wood trim) Supercharger has 10% 2.5 psi pully on it
