Hello, I remember reading about a bracket both the Throttle cable and the Cruise cable mounted to. Ford had to add a clip to secure the Cruise cable because the Cruise cable was rubbing the Throttle cable.
Next, Ask your Dealer about the Recall for a part called "Cam Phasers". I know that 2004-2008 Models with 4.6L and 5.4L engines were included. Your car only comes with a 4.6L engine. There is an Extended Warranty of 7 Years and I want to say 90,000 Miles. The Mileage amount keeps changing.
The "Cam Phasers" were used on the DOHC models. The older design uses 1 cam and would have a SOHC Emblem on the Engine. The delay and lack of pep can be caused by valve lag on the DOHC engines. The Phaser was suppose to auto-advance the valve timing but since there were 2 in each engine one bank could be set differently than the other, a terrible condition.
You might try to clean the MAF sensor in the air intake with Electronics cleaner. There is a switch on the Airhorn that has a TPS, throttle position sensor that may not be smoothly picking up your throttle changes. It is the switch attached to the Air Butterfly Plate. Beneath the Air Horn there is sometimes a groove under the Airhorn gasket. This feeds the EGR and makes a difference if it is clogged or clean.
About the only other things to check is a part called the "Idle Air Solenoid" which is the round cylinder object, it has a floating valve that can get dirty and responds to WD40 and to check for Vacuum leaks with a water mist spray or approved choke cleaner (safe for plastics and rubber" while the engine is running. The RPM changes when a leak is found.
I hope my solutions are helpful. You have a lot of new information to check. Would be interested in which solution cured your problem.
