If your suggestion fixes the problem then you will get $50. So far this problem has lasted one year and not a single suggestion from any of the forums has provided a solution that eliminated this stalling.

Rules: You must state step by step the procedure that you would undertake. It must be replicated by an idiot like me and will not require that I end up in the hospital. In addition, replacing the whole engine or complete systems are not acceptable solutions. You must pinpoint a specific problem, support it then list and describe exactly how you would go about it.
Before I implement your solution it must be vetted. Once I agree to go with your solution there will be a testing period of two weeks before I declare you a winner.
