i have a 08 g37s coupe and recently i have been getting the safe mode problem which has been locking my car at 2500 rpms and if i try to go past it the car starts to jerk violently. I dont really know what the problem is whether is a sensor issue, throttle body, or even ecu i dont think its the ecu because when i rest the ecu using the video on youtube it works fine then like the other day i was driving and i pulled up to a red light and hit the gas a little and the car jerked really hard almost causing the dude behind me to rear-end me and the car went in safe mode. about a month ago this problem started it would go in safe mode i would reset it and it would work then like a week later it would happen again but now im at the point that when i reset the ecu it happens alomst everyday it always goes into safe mode. HELP PLEASE
