My 2002 M Mountaineer had the same problem and was fixed by reading the code that showed a leak in the gas tank pressure via the cap. When I replaced this with a good after market cap and drove the car for a while and it cleared itself. A mechanic told me that's not possible, but it did clear and has not lit up except on start up where it lights for a few seconds to test the bulb - a normal function.

PO 300 is multiple misfires detected
PO 301, 304, 305, 306 are misfires in cylinders 1,4,5,&6
PO 053 is HO2S Bank 1 Sensor 1 Heater Resistance
PO 106 is MAP/BARO CKT Range / Perf
PO 316 is Misfire detected 1st 1000 Revs.
On a misfire, I usually push towards the spark plugs, plug wires, and coil packs / distributor coil.
You have PO 106 and PO 053 that need to be inquired about at nearest AutoZone.
They can give you an idea as to what is the problem on these.
Did a MAP sensor **** out and cause all the misfires ?
Did a misfire cause the MAP sensor error?
You see what I'm saying ?...Something caused all the misfires...thinking MAP...but not that familiar with the function of the MAP.
Hope this helps...
