Yes, if the engine is turning when the timing belt breaks, the valves will hit the piston. This is the definition of an interference engine: the valves, when fully open, extend into the cylinder area.

What is DWG? Don't wanna go? Doesn"t work good? Dirty with goop?

The idle air control motor may be defective/sticky. The computer gives it a command but doesn't realize the motor is not following the command and therefore no check engine light. You can remove the IAC and try to clean it with carb spray

Most likely an emission related issue. O2 sensor,egr or evap problem. You shouldn't experience any drivability issues as the code is a soft one and doesn't keep the light on. It wouldn't be a bad idea to have it checked regardless for piece of mind.

Mine has a high pitched whistle at high rpms and I can't figure it out. But mines def not the tranny. I'm thinking it's a vacuum line somewhere. It's a 97 2.3l manual. The colder it is the louder...

Should idle between 550 or 650 RPMs. If it wont stay running under 1000 RPMs there is something wrong. Idling at or above 1000 RPMs it' going to be slamming into forward and reverse.

Which wire are you grounding? http://easyautodiagnostics.com/ford/4.9L-5.0L-5.8L/fuel-pump-relay-tests-3

nope

Try TPS. Throttle positioning Sensor. This sets base idle. (Unless this model is too old for that sensor)

Check fuse able link a fat wire running from positive side of battery to fuse block in the engine compartment.

Throttle position sensor

Got to have proper grounds attached, or you may have ruined the unit.

Knowing how to work on braking systems? Education My guess --replace a failed rubber flex hose I don't know how much moisture & rust is in the system, so is the caliper seized also

Check for water in the tank and fuel lines and the filter.

Clean throttle body,change air filter & fuel filter,put some fuel cleaner first.

is this carburated or fuel inj , if carb , the choke is stayin open , shoud work automatically if efi

Common problem. T/S lever is part of the "multifunction switch" that controls hi/lo lamps. It can be replaced by removing the lower shroud (3 or 4 screws from the bottom up). SW1093 @ Auto Zone about $66.

Check all the connections to be sure the wires are in good condition. Check the battery terminals and make sure they are making good contact. Make sure none of the pins on the alternator are not bent and are lining up with the connectors. Be sure none of the wires are pulled out of the connectors. Use a Volt meter to check the voltage at the alternator and at the battery. It should be between 13.5 and 15 volts. Also check the grounds to the engine. I hope this help you locate the problem.

If you could post more Information about the vehicle it would help. Is it a 4 cylinder or V6, and have you change plug wires or done any other repairs. Unplug the mass air flow sensor at idle and if the engine quits then the problem is not with that sensor, it is else where. It could have a bad timing chain and jumped time or if the timing belt on a 4 cylinder is worn out it could also jump time and cause a lot of damage. I don't know what else to tell you. I hope this was helpful.

It seems I have more questions that need to be answered. Have you got any on board diagnostic codes. If not you need to hook up a code reader to see if it is storing any codes that will let you to the problem. Most generally the lose of power is related to the timing and is controlled by the O2 sensors. another this is the mass air flow sensor located on the air intake tube next to the air filter. I hope this has been of some help. Good Luck
