One of my friends had an Escort that did the same thing. The Air intake tube between the air-flow meter and the Throttle body had a hole it. As soon as I sealed the hole up it stopped. Make sure you check for leaks between the AFM and the THB. You might get lucky and it's something simple like that.

Right, the coil on hers will be on top of the power steering pump bracket. Extremely easy to replace.

Most likely, but it's possible that it's not. As long as a sensor is still within it's range of operation, then it won't throw a code. But it can be "on it's way out" so to speak, and not be functioning very well, but still be "operational" so the computer won't throw a code. This is what happened to me when one of my MAF's went out. I ended up just having to test every sensor I could find, MAF, IAT, IAC, TPS, O2's etc. etc.. Finally just replaced my MAF with the Pro-M i had sitting in my toolbox, and BAM! had all my power and mpg back.

FWIW, Have you seen this wire (harness) on our cars? It's not just a simple wire like the old days.
There is no aftermarket replacement, and from the dealer list is over 320.00
Sound like they did the only thing resonable.
You'll have to split the harness and separate it all out to change out that one wire. They'd probably charge you more than the 320.00 just in labor to do that.
