It sounds like you have and unusual and flawed driving technique.
Manual or Automatic?
Automatic. You never use neutral unless you are in a car wash that drags your car by the wheels. Decelerate, foot on the brake and into Park. Your right foot does both brake and accelerator, left foot does nothing. I saw a lady 2 days ago with left foot on the brake and right foot on the accelerator.
Manual. Downshift through the gears, right foot on the brake, left foot on the clutch and into neutral and hand brake on.
If you are doing that, the vehicle needs diagnosis why it is happening.
Check for codesThat has been the first thing you always do, for the last 30 years, with any vehicle issueI don't know what you mean-- goes to idleThe transmission comes out of gear ?
Hello. The 'Schrader valve' is, usually, somewhere on the 'fuel rail' of the engine; the assembly the fuel injectors are in. It's like a bicycle tire valve one puts air through. That 'valve' has a colored cap on it and is there to check p.s.i of the 'incoming' fuel AND pressure in the 'fuel rail' itself. Good luck and keep me informed; if you want to.
Sometimes your car insurance will pay for this as a fire claim. You do not have to fix it yourself. My Olds lit up the dash, the insurance covered it and a Rental.
As for the 4 fuses there may be a fusible link to power these. Also since most are only required when the engine is running, they may be dead until the ignition is turned on.
Not familiar with the 500, but a MAP Sensor is a little 2"x3" black plactic box. with a vacuum line and wires hooked to it, usually located on the firewall with 2 screws.

You are in luck, a 2005 Ford Five Hundred Key Fob Remote is self programmable. Now these procedures can be a bit frustrating at times, so be patient, it's all about timing. If you get it programmed on the first try you are among a very few talented programming individuals! Also, if you need an affordable key fob replacement for your Ford Five Hundred, buy it here:

Here are the programming instructions:
FORD REMOTE - THIS PROCEDURE RESETS ALL REMOTES FOR THE VEHICLE. ALL FUNCTIONING REMOTES WILL HAVE TO BE REPROGRAMMED DURING THE PROCEDURE There are a few different procedures that will program your remotes depending on what vehicle that you have. You can find your exact procedure in your owners manual. If you do not have your owners manual you can try any of the procedures below until you find the one that works for your vehicles
Make sure that you don't press the brake pedal at any time during or before the procedure.
Procedure A:
1.Close all doors, then open drivers door and press the Unlock button on driver's door while it is open, insert key into ignition.
2.Turn ignition from OFF to RUN 8 times within 8 seconds, with the 8th time ending in RUN. Door locks will cycle to confirm programming mode. (if the door locks do not cycle, then it was done incorrectly. You must start over by removing key and beginning from step 1)
(Off is the position where you can remove your key, RUN is the position just shy of starting your car.)
3.Within 10 seconds press any button on the first keyless remote to be programmed. Door locks will cycle to confirm programming. If you only have one remote then skip to step 5.
4.Within 10 seconds, press any button on the second keyless remote. Door locks will cycle again to confirm programming. Repeat step 4. for all other remotes.
5.Turn ignition to OFF. Locks will again cycle to indicate end of programming mode.
*If this does not work try the procedure with the door closed.
Procedure B:
1. Fasten seatbelt and close all doors
2. Turn the ignition from OFF to RUN 4 times within 3 seconds.
3. Turn the ignition OFF. The system will chime to confirm programming mode.
4. Within 10 seconds, press and hold any button on first keyless remote. The system will chime once to confirm programming.
5. Within 10 seconds, press and hold any button on second keyless remote. System will chime once to confirm programming.
6. Turn ignition to RUN to exit programming mode.
Please note: All steps should be performed in fairly rapid succession. If you never get the initial chime or door lock cycle, that means the vehicle has never entered programming mode. You should remove key from ignition, open and close the door and start over.
The idling may be a loose connection to the "idle air control valve". if the control valve connection is secure, then it could also be a bad Throttle Positioning Sensor (TPS). To test the TPS, tap it with a screwdriver while the engine is self-revving, and see if the reving changes when tapped. if its not the TPS, then try cleaning the throttle body.
I doubt water is your problem. Gas with ethanol is at least 10% alcohol. So a half tank of ethanol gas has a zillion times more alcohol than a bottle of heat.
