I have a 1997 ford expedxition 4wd 5.4 my check engine light is on and autozone checked it for me the codes were P0174 and P0307.P0307 said there was a misfire in cylinder 7 the plug and coil are both new what else could cause it to misfire I am thinking maybe the fuel injecter is there a way to check the injecter to see if it is working? P0174 say bank 2 has a rich or lean air/fuel ratio possible cause if bank 1 and 2 are set together possible pressure condition, or failed heated oxegen sensor bank 2 sensor 1 not sure where this sensor is located. Also not sure what bank 1 or bank 2 means lol. Appreciate any help I can get with this problem!

P0307 is cylinder #7. Check spark plug and replace ignition coil . p0174 is a vacuum leak. Check vacuum hoses on top of motor. Normally you can hear the leak
