My check engine light is on. Ford dealership says they're getting an error for the oxygen intake sensors, but the sensors themselfs are fine. So that means there's a short in the wiring. They say that'll take 3 to 5 hours to diagnose which wires are causing the problem, though. Which is going to cost me like $500.
Why that long? If it's getting an oxygen sensor error, wouldn't that mean the wires to and from *those sensors* are the ones that are bad? Why do they have to check all of them?

If you've ever had to partially or entirely remove a wiring harness from a car, open it up, isolate the defective wire(s) and repair or overlay them, you'd know why it can take so long. More to the point, if they're an honest operation the price they quoted you is top dollar. If they find and repair the problem sooner you bill will be less... maybe substantially.
The alternative is to keep driving your car the way it is until the driveability issue causes something like a destroyed catalytic converter. Then you'll wish you stepped up in the first place.
And just for the record, anyone that tells you it's a waste of money is a moron.

It sounds easy.
First thing they should have done is replaced the sensors. If that doesn't fix it, they have to dig deeper.
Consider that a typical sedan can have over 10 separate control computers, and several miles of wire. You're talking about a signal path that goes from underneath the car, through at least 3 larger wiring harnesses, back to the engine's control computer. Those 8 wires (4 for front sensor, 4 for rear sensor) go all through the car before they end back up at the computer.
If they're smart, they can check continuity at each wiring junction, all the way back to the ECU. They also need to eliminate the ECU as the problem. That will take time.
Just hope they don't have to take the car apart to replace a chassis harness.

Thats a lie to gain more money. don't go to the ford rep, they are a rip off. I had a fleet of 13 ford vans and ford screwed me on price several times. I got a contract with a smaller family owned chain and for some odd reason my fleet repair cost dropped to 25% and I had much less break downs.
if they're checking wires its not to hard to find the corrupt wire. especially with an o2 sensor. I replace several wires on my 02 taurus and it took me about 2 hours. go some place else!

You are right, sounds like a stall to me. Ford has the complete wiring chart and can follow the circuit from the o2 sensor .to anywhere.
3-5 hours sounds like thy are guessing and just fig er if thy price it hi, you will take it someplace else
