Why would you just buy a used computer instead of reading the codes with a scan tool and fixing the issues that put it into Limp Mode. It is often something as simple as replacing a $18 sensor. Your ECU needs programming with VIN Number and the mileage so you need an auto-electrician anyway.
Rough idle is probably a throttle body and MAF that needs cleaning or they may have failed. It may also be the Throttle Position Sensor. Limp Mode keeps you in first and 3,000 rpm. Limp Mode only saves you from damaging the engine. Get it on a pro grade scan tool computer in a repair shop.

It's in the under hood fuse box . Free diagram here http://www.bbbind.com/free-tsb/ Enter vehicle info. Year , make , model an engine ., Under system click on electrical distribution , then under subsystem click junction block . Click the search button then the blue link . At the bottom of the first diagram you'll see the fuel pump relay location . Just in case you are unaware of the electronics involved in the fuel pump electrical circuit for this vehicle , it also has a fuel pump driver module .
Electronic returnless fuel system . Suggest you watch this video

the battery is probably badly sulphated and has cell problems
use a load tester to check the battery
after that use a scan tool to reset the ECM program as the CPU is corrupted
It is true some climates are unkind to rubber components but in fairness rubber components arrive in a wide variety of qualities and differing materials and mostly you don't know what you have until it begins to go wrong.
Being an organic product (rubber tends to have more in common with oil and chemistry these days than with rubber trees) it can be adversely affected by sustained high temperatures, ultraviolet radiation and by absorbing substances from the immediate environment.
I doubt Armour All will be any help and there is the added problem of accessibility in order to treat the rubber and rubbery components of your car - of which there are many.
In most districts there is to be found at least one general industrial supplier that supplies things like bearings, hydraulic components, driveline systems and components and a host of specialised oils, greases and chemicals to industry and construction. They also make and repair things connected to those industries and many other people. Such businesses are invaluable in any community and are a mine of information.
The cost of some of the rubber components they supply would make your $200 engine mount seem positively paltry. If a treatment exists to make rubber components last longer they will know about it and I am certain they would be happy to tell you about it.
Good luck!
It is under the throttle body area and it is hard to get to unless you are doing the plugs and have it out of the way. My Ford dealer quoted $166 to change the plugs P&L. I did them myself. Look up your PVC valve on rockauto.com to see what it looks like.
1. Remove the 4 transaxle roll restrictor brace bolts.
o To install, clean the bolts using a wire brush, apply new threadlocker to the threads and tighten to 55 Nm (41 lb-ft) .
2. Remove the bolt and the transaxle roll restrictor brace.
o To install, clean the bolts using a wire brush, apply new threadlocker to the threads and tighten to 48 Nm (35 lb-ft) .
3. Disconnect the positive crankcase ventilation (PCV) valve tube from the PCV valve.
4. If equipped, disconnect the PCV valve electrical connector.
5. CAUTION: A new PCV valve must be installed if removed from the cam cover. Damage will occur to the locking mechanism on the PCV valve. Rotate the PCV valve counterclockwise to remove from the valve cover.
6. To install, reverse the removal procedure
Hello!
The computer turns this light on when there is a powertrain malfunction/electronic throttle body system malfunction. It could be the throttle body, computer, wiring or a sensor into the computer used for the throttle body. You will need to scan your computer again when the code is illuminated on the dash. Chances are you will pick up a code when this is done in the computer.
Accelerator Pedal Position (APP) Sensor
The APP sensor is an input to the powertrain control module (PCM) and is used to determine the torque demand. There are 3 pedal position signals in the sensor. Signal 1, APPS1, has a negative slope (increasing angle, decreasing voltage) and signals 2 and 3, APPS2 and APPS3, both have a positive slope (increasing angle, increasing voltage). During normal operation APPS1 is used as the indication of pedal position by the strategy. The 3 pedal position signals make sure the PCM receives a correct input even if 1 signal has a concern. There are 2 reference voltage circuits and 2 signal return circuits for the sensor. For additional information, refer to Torque Based Electronic Throttle Control (ETC) in this section.
It should be noted that the ETC system includes a warning indicator, wrench warning indicator, on the instrument cluster that illuminates when a concern is present. Concerns are accompanied by diagnostic trouble codes (DTCs) and may also illuminate the malfunction indicator lamp (MIL).
You best bet is to take your vehicle to a ASE certified repair shop or the Ford dealer !

TCC solenoid. This is for over drive. This is an internal transmission problem. Could be just the solenoid. It could be OD clutches. If you have an OD switch, keep it turned off/light on. If you don't have the money to repair it right now. Stay off the highway.
You can't reset it. They all come with a factory code (RKE Code). If you have the factory code you can add a second and third code of your own. If you have lost the factory code you can retrieve it by going to the Ford dealer. Secondly you can do it this way:
Location for key pad entery code; 2006 Ford 500. Need to pull panel off below steering wheel (I used a 9/32 socket) Then look for 3 10mm nuts, 2 @ top 1 on the bottom. if you are having trouble locating this box, its part of your fuse box (says pull on the cover) and your fuses are behind the cover. Once you have removed the 3 10mm nuts, look on the back of the box (CAREFUL NOT TO PULL ON WIRES TO MUCH) and you will see the 5digit code! Watch this you tube video.

I hope this helps.
When the car detects something it needs service for, it will lit the wrench. If the lamp is not defect. (you can check during startup, because it will put on all lights) the cause for switching on is gone. Could be something like a low oil reading. Without the diagnostic computer connected you can't tell what is (or was) wrong. Only in a service centre they can.
As soon as a RED warning light goes on, it is better to stop and call a service centre. With one of the orange or yellow light on as a warning, you should be able to reach a service centre yourself. When it is in a reasonable driving distance.
If it is locked in park, it could be the brake switch or the shift lock solenoid. You may be able to shift out of park before you turn the key switch to the on position.
One of 2 ways. Disconnect the battery for 10 minutes to clear the brain or go to a Big Three autoparts store like Autozone, Advance, or Oreilys and have them do it with a scanner.
