So this morning, truck started fine then faltered and died just like the first time at 20k when a valve spring broke. Same service electronic throttle code and same behavior. Truck is scheduled in for service tomorrow and I am waiting on a two truck now. Wondering if anyone else has been through this same issue. Likely not since i always get the unique ones with my vehicles. But just in case, if you have, did you ever find out the root cause?
