K I pulled a p1000 dtc from my 97 f150 4.6 r470w

the p1000 comes up as continuous OBD Systems readiness Test not complete?

On the live data display fuel sytem shows Ok and online.
then when I move the truck or park on a hill it shows cl fault then tells me it is running in a closed loop mode.

What could be a possible cause?
Engine lacks power vacuum holds

still have 4 injectors all on the passenger side that will not click or work unplug them no change in idle.
Checked for power all got 13v on the positive sideof injector harness
check signal on ground side of harness voltage is 3-5 v on #1 and #7
3&5 average 9-10 v
I have no idea why
all 4 injectors on the drivers side work unplug any one of them and the idle is affected.
truck idles rough at 750rpm -820 rpm
tps is at 20 %
iat and ect all in spec
maf also in spec

emmisions for Im monitoring shows 1 pending code p0161
o2 sensor

On a side note live data shows I got
0% for L.T.F.T and 1.5 S.T.F.T on bank 1
S.T.F.Tflucuates but Always shows 0% for L.T.F.T

bank 2 shows Good LTFT and STFT

Any help would be greatly appreciated...
Plugs are oem and new coil packs are tested and good
wires are new

Vacuum holds and returns to Average 20-24" hg

has nothing to do with your problem. readyness monitors are set by the computer running its tests. your truck has not completed the drive cycle since you have cleared codes, disconneted the battery or computer. means nohthing to do with a driveability problem.

If you have power to the injectors, but no control. its wiring problem or computer.
