I don't think its neither of those joemom because the car starts perfect every time I turn it over I'm thinking that it maybe the Massive Air Flow Sensor for it run rough in drive or reverse but the engine run smooth when in neutral or park.

What if is runs really rough while in park or drive and continues to run rough until it reaches about 20 MPH then runs fine?
