Need help mustang missing

Ok guys so I bought another mustang. Nothing special just something to drive everyday. Anyone the car is driving me nuts and it has a miss. When i plug my colde reader in this is what its saying. . . . . .

1- P1443 Evap emission ctrl system ctrl valve
2- p0155 sensor Heater circuit bank 2 sensor 1
3- p1152 Lack of Ho2s21 swithch sens indicater rich
4- p0175 system to rich bank 2

Any idea if any of these is casuing the car to miss? Also if it is one of those what would be the fix?

The car misses when your just giving it anywhere from 1/8 to 3/4. But if you put it to the floor it clears itself up.

PLEASE help guys i'm starting to go nuts!!!

I'm not a DTC guru, but based on my limited knowledge, the first things I'd check for would be the O2 sensors, and vaccuum/exhaust leaks.

WMBurns will probably come in here and tell you exactly what's up in his own special way... But if I'm not mistaken, your ECM is trying to compensate for a lean condition by dumping excess fuel.
