Have Jeep Questions? Ask a Jeep Repair Expert for Answers
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.As long as the engine did not over heat and you had plenty of oil in it then there really should be no damaged caused as the engine is designed to handle this type of RPM even with no load on it. The system is designed to shut down the fuel pressure if the computer sees an over revving condition. I suspect as you do, this problem was likely a programming concern and you should be fine once they get it resolved.
