Happy to report that the dealer got the problem fixed, Loose pins in connector to throttle. Car has been ok for 1000 miles. Impressed with the high quality if dealer service, They stuck with the problem until they were confident of the fix, Will get all future service work,

My wife has a 2011 XK. We have only put 25000 miles on it when the restricted performance triangle came on. It has happened every 300 miles or so since then. It always happens when accelerating from a stop or slow moving 5 mph position. Only once did the car go 2000 miles before failing. I shut off the engine and wait 2 minutes. Car restarts and performs as normal until the next episode. probably 8 episodes in the last 4500 miles. I took it to local Jag dealer who replaced ECM (big bill) to no avail and then replaced throttle actuator {more bucks). When it continued to fail they said all the codes checked out and basically walked away from it. I took it to a local independent garage who checked wiring and air systems. So I rook it to a jag dealer 120 miles away. I am impressed with their professionalism and diligence but it has been 2 months and still not fixed. Has anyone had similar experience with failure at low speeds?
