1996 JAGUAR XJ6 User Comment / Complaint

Accelerator pedal appeared to stick. when pedal was released, engine did not throttle down, resulting in revs remaining at previous level, and speed unchanged. when driven on the highway, this means that speed remains at 55 even when accelerator pedal is not depressed. sometimes, runaway acceleration occurs. i took vehicle to my mechanic. he rebuilt the throttle body. problem unsolved. he then did some research and found that there was a defective design for the 1996 throttle body, which was subsequently changed. he installed the new design, and the problem went away. i reported it to jaguar usa. they said because the vehicle was out of warranty, there was nothing they could do, but they would send me $100 "boutique dollars" as a gift. incident date is approximate.  view
