vibration NOISE during acceleration...
When the vehicle (94 f/s bronco w/ 5.0 HO and 74,000 miles) accelerates there is a SOUND of vibration coming from the passenger side of the engine compartment near the firewall. I have heard about the check valve going bad but never heard what it sounds like when it does. If it is the check valve, how the heck do they expect you to replace it other than the simple remove the clips and hoses, remove the part and install in reverse order. Hah, there is not quite that much room back there. It almost seems as though you should remove the upper intake. Any and all help is greatly appreciated.
