Just the other day my 2000 4.0L Ranger XLT started running rough, I have pulled the codes and have got :

P1151
P1152 - Pending
P0306
P0175

when I tested it at first the code P0306 never showed up, it showed up after I cleared out the original codes.

my Freeze frame information is as follows :

DTCFRZF ----- P0306
Fuelsys1 ------CL
FuelSys2------N/A
Load %-------80.4
ETC (degres C) 93
Shrtft1 (%)---- 1.6
Longft1(%)---- -0.8
Shrtft2 (%)--- 42.2
Longft2 (%)---- -2.3
RPM (/min) ---- 1686
VSS (km/h) 84


My symptoms are bucking and jarring under any load, and significant loss of power, I thought it may have been my downward O2 Sensor but I changed that out and it was fine, I took out my #6 plug and that did nothing. I checked my MAFS and it is fine as well. Any help would be greatly appreciated.
