Mechanics sad that this is ignition key error (something with the coded key-felt on a ground etc.) but I found that it could be head gasket error, too. Please help

This code is not documented so the code reader is giving a false reading.
If the car runs OK and check engine light is not on, I would forget about it.
SOURCE: Check Engine light
that code definition is "Evap high purge flow fault". It means you may have a problem with the evaporative system. this system routes fuel fumes back to the fuel tank. If you want to try and clear this code, find the radio code for your car and then disconnect the battery for 30 seconds. Reconnect the battery and the check engine light should be out. You will then need the radio code to reset your car stereo. the check engine light may stay off if the condition was a transient one. If not, the light will come back on after you drive the car two drive cycles. That is: two starts, warm ups and shut downs. If the light returns, have a mechanic check it out.
SOURCE: My 2003 Kia Spectra has Diagnostic codes: P1404 & P0444.?.?
the purge valve i believe is located near your gas tank unless theyve moved it i should look like a little canister cyclinder shaped. both codes could be set off by the same problem. try replacing the valve.

Replace the coil pack once more. I went through 2 new ones on my f150 on one cylinder. One worked, the other didn't (both new off the shelf). Condensation build up in the boot caused mine to misfire. Anytime you replace a coil pack, squirt a little silicone grease inside. This will prevent condensation from hitting your plug. Fords are notorius for this problem, especially if you live in a humid area. Also, make sure and clear the codes after you make the repair.

Using a scan tool, watch the MAP sensor value with the key on, engine off. Compare the BARO reading with the MAP reading. They should be roughly equal. The voltage for the MAP sensor should read approx. 4.5 volts. Now start the engine and look for a significant drop in the MAP sensor voltage indicating the MAP sensor is working.
If the MAP reading doesn't change perform the following:
With the Key on, engine off, disconnect the vacuum hose from the MAP sensor. Using a vacuum pump, pull 20 in. of vacuum on the MAP sensor. Does the voltage drop? It should. If it doesn't inspect the MAP sensor vacuum port and vacuum hose to manifold for a restriction of some kind. Repair or replace as necessary.
If there are no restrictions, and the value doesn't change with vacuum, then perform the following: with the Key on and engine off and the MAP sensor unplugged, check for 5 Volts at the reference wire to the MAP sensor connector with a Digital Voltmeter. If there is none, check for reference voltage at the PCM connector. If the reference voltage is present at the PCM connector but not the MAP connector, check for open or short in the reference wire between MAP and PCM and retest.
If reference voltage is present, then check for existing ground at the MAP sensor connector. If it isn't present then repair open/short in the ground circuit.
If ground is present, then replace MAP sensor.
Trouble Code: P0722
A/T Pulse Generator 'B' Sensor Circuit Malfunction
Possible Causes:
Pulse generator 'B' (+) or (-) circuit is open or shorted to ground .
Pulse generator 'B' is damaged or has failed.
TCM has failed .
TSB 01-40-006-1 (12/01) contains information about this code.
Trouble Code: P01529
Customer Snapshot Request Error
Possible Causes:
Transmission control module error.
Check for trouble codes in the transmission control module.
TSB 1-40-005 (3/01) contains information about this code. I have info. on these 2 codes,will search more for the others.
