i have the same problem with my 2005 murano at 16k. they replaced the throttle body sensor. then it happened again at 28k; same failure code came up on their computer. this tells me that something else is wrong and the computer is only picking up a symptom of a bigger problem. both times the service mgr said that its the only time he' ever seen this happen to a murano. does anyone think it could be a defect in the transmission? oh, and the check engine light did come on.
