Fuel Delivery Problems of Jaguar XJ8

I have a 1998 Jaguar Xj8. The vehicle stalls at high speeds, generally after I accelerate over 50 mph. The vehicle is extremely difficult to control and can only be restarted if you bring it to a stop. I had this happen while driving the car in CA. I was almost killed when the vehicle stalled. Jaguar dealer, santa monica,repaired as cyl burn out. Mechanic told me stalling happened frequently with this model. A few years later,san antonio TX on the 183 highway rush hour. Car stalled causing me to swerve next to center median ripping off the engine cover on debris. Jaguar fixed throttle body not engine cover. Service bulletin, defective throttle body. Car ran poorly thereafter. Stalled again year later. Dealer would not repair. $3,000 to fix. . Recently discovered consumers world wide have same problem. Service bulletin repair only short term fix. Jaguar blog in the uk -consumer discovered from a Jaguar mechanic , most throttle bodies needed to be cleaned periodically as the lining bad and build up or deposits would form on the walls of the throttle body and cause it to malfunction. My mechanic had heard of similar problems. I called several Jaguar dealerships. I was told, off the record, that I could clean the throttle and get by, but certain cleaners would cause the lining to deteriorate. I was told the replacement was a rip off, off the record. Using the appropriate cleaner, the assembly was cleaned without removal. When we turned on the vehicle smoke billowed out of the exhaust for several minutes and then subsided. The vehicle now runs perfectly. Jaguar is profiting from replacement of parts that could be cleaned and need top be cleaned regularly. Replacements effective short term only. Your form allows only "s" type equip". This is a Xj8.
