Ahoy,
 
I've recently encountered the same problem as described above in these last two posts after returning from a long mountain trip back home. I have a '99 XJ8 and the throttle stuck as I tried to break at the first traffic light. Didn't want to stop but after hitting the brakes hard and steady, it slowed, shuddered, stopped and stalled. If I hadn't reacted quickly enough, I would probably have plowed into a vehicle at the light. Ugh! My now disappeared mech told me last year the throttle body would probably need some work or costly repairs down the road, and he was right. It won't start at all now and is sitting in the drive till I sort all my options out, plus already bought a '97 XJR, heh heh! Double trouble eh? Stability Control Failure light is on the dash, already located the inertia fuel disconnect switch under the passenger floorboard, which wasn't triggered, and already disconnected the battery to see if it's an ECM issue as to why it won't start. Any ideas out here?

Fail Safe comes on at times when using cruse control. Cut engine take key out and back to normal with no Fail Safe showing.

Hi Denham,
 
Thanks for this info. I can't remember now if I had turned off the cruise switch on the gear console when this situation occurred now, but stopping the vehicle and trying to get it started again was a battery draining waste of time. It's been sitting in my driveway since the incident while I pondered the best possible solution to it's diagnosis and repair. My solution so far was last Monday,,bought a '97 XJR, LOL! Already had issues with it, being christened in with a new alternator after the old one fried to a crisp Saturday morning. Been a real dramatic week! The only OBDII code on the XJ8 showing is a pending P1112 which translates to an Air Temp Sensor issue which shouldn't be a major concern. It also shows the Stability Control Failure on the dash, but that is an amber code so it should at least still start right?
 
Cheers,
Jagzilla
