Glad you are on the road again. This is a picture of my road call problem I was describing..

cute little fella. We see from time to time air filter boxes filled with dog food or pine cones. They can fill these boxes pretty quick. We had a mouse in our second house a few years ago. We had a large dog food bowl for our English mastiff. One morning it was empty and didn't think much of it. Then we opened up the sink cabinet and found it all inside. That little guy moved roughly 2LBs of dog food in a single night with trips about 15' each way.

I just recovered from the identical problem. Engine would not respond to accelerator pedal, idle was OK, fault codes P2112 and P2104. Problem occurred pulling into a Sam's Club gas station to top off the fuel tank after a weekend trip. I was able to idle to a corner of a parking lot and waited for a tow to get me home, 5 miles away.

Next day in the drive way pulled the dog house and started checking. With engine running throttle body had no response to pedal but with the engine off but key on the throttle body would respond but was very noise. With the engine off and key off the butter flies were very stiff and difficult to move by hand. This confirmed the P2112 code, stuck throttle, and the P2104, forced idle.

Pulled the throttle body and started taking it apart. Figured had nothing to lose. When I pulled the throttle servo motor cover found one of the motor magnetics had come unglued and was jamming the motor. Re-glued with two part epoxy, clean the assembly and reinstalled. Fault codes cleared and I was back at Sam's for gas. Total cost about $4 for a can of cleaner. GS ERS tow was free.

Good fix and tip.

Thanks,

I had my throttle body quit at 67K miles! Turned out the magnets are glued to the case on the dc stepper motor that controls the butterfly valve through a transmission or gears. The glue failed and both magnets ended up stuck to the armature. This is a single point failure that occurred due to bad design and/or production fault. This failure is probably more common but isn't being investigated. See post #17 for the simple fix of regluing them back on. I'd add a small flat head screw to the center of the magnet and up through the casing.
I filed a complaint with NHTSA since there are already lawsuits out to Ford on the THB for several other models. My engine is a V10 on a class C motor home.
It cost two days on the road and $1600 to fix. I'd like a little of that back.

Before you get towed try and get the throttle body off and take the motor casing off to see if it's the magnets. you might be able to glue them back in place and get back on the road!!
