Just curious if this means that sometime in its life the map sensor read out of range or if this means it needs replacing. Car has a bad surging idle problem and no power under accleration sometimes, and this is what the scanner spit out. I should mention as well that there is no check engine light being set. THanks in advance.
Code 22

Most likely you're getting Code 22 for Ignition problems but Do this Checklist for Code 22:
1) Locate the Map sensor (near the firewall) and verify that the vacuum hose is firmly plugged and all the wires firmly attached to it. If everything looks firmly attached go to step 2.
2) Verify Coil Pack, Distributor assembly and T.F.I. module (Thick Film Ignition Module) if any of those ain't doing its job your car will react like you described.
I had another Ford car with TFI problems and the ECIV computer would give me a "false" Code 22 when actually the problem was originated by the TFI module and the old Coil Pack.
Just some ideas for your car. I hope that helps.

You can disconnect the MAP sensor as a test.
The computer will substitute its own default values for the missing sensor so you can see if the drivability symptoms change. You will, of course, get a CEL while operating under this test condition, but your goal is to see if performance changes with the sensor unhooked.

THanks guys, I was in the salvage yard this weekend anyways, so I grabbed a spare MAP and IAC to try out. Lets hope the car wasn't junked for faulty MAP or IAC now. I'll look at the IM next as well.....that might be a likely culprit. SHe mentioned that she had a stalling problem before and the shop changed the plugs and sprayed out the intake (IAC likely) and that seemed to solve it (this was that tune up discussed earlier

) so this idling problem may be related.
Just a quick thinks for the tips. Turns out it may have been the MAP sensor all along. I swapped it out with the JY one and it cleared the idle up and the accelerating problem.....at least for the last couple days. Maybe we got lucky. Well on to the next project that I'm sure will bring some more questions...
