1999 Jaguar XK8

SUDDEN LOSS OF POWER. THIS IS DUE TO THE STABLIITY CONTROL CHIP LOCATED IN THE THROTTLE BODY GOING BAD. WHEN THE WHEELS BREAK LOOSE, A SENSOR SENDS A SIGNAL TO THE CHIP IN THE THROTTLE BODY TO SLOW THE ENGINE SO IT DOES NOT OVER-REV. THIS CHIP ACCORDING TO THE DEALER IS MALFUNCTIONING AND 'FIRING' ON ITS OWN RESULTING IN A SUDDEN LOSS OF SPEED. THIS FIRST OCCURRED 18 MONTHS AGO AND I HAD TO REPLACE THE THROTTLE BODY ($1800). IT JUST STARTED TO HAPPEN AGAIN AND THE NEW THROTTLE BODY ONLY HAD 13K MILES ON IT. I JUST HAD TO REPLACE AGAIN AND THEY ONLY CHARGED ME ANOTHER $730. MY WIFE DRIVES THIS CAR AND THIS IS DANGEROUS AS SOMEONE ALMOST REAR ENDED HER. I KNOW THAT THERE IS A DEALER ADVISORY REGARDING A SIMILAR PROBLEM WITH ANOTHER JAGUAR MODEL. I SAVED BOTH THROTTLE BODIES SO YOU MAY BORROW THEM IF YOU WOULD LIKE. OTHERWISE THEY WILL BE SOME EXPENSIVE BOOK ENDS. WE WILL NOT OWN ANOTHER JAGUAR DUE TO THIS RECURRING PROBLEM BUT I HOPE SOMEONE DOES NOT HAVE TO DIE BEFORE THEY START TREATING THEIR CUSTOMERS RIGHT ARD CORRECT THIS ISSUE.
