I own a 2004 XG350 the same happend to me I disconnect the battery and connected again then i start the car and the problem went away you should try this before buying anything
Just wondered if you found anything that worked. I am having the same issue and the dealer recommends a throttle sensor and cam sensor for a ridiculous amount of money. Please let me know what worked
