I have a 2002 ford with 50,350 miles on it. I just replaced the serpentine belt, fuel filter, air filter, oil, oil filter, pcv valve, and plugs. I am getting a very loud chirping noise from the top of the engine when at cold idle, it increases with rpm's and is much quieter when at warm idle, any ideas?
