Kevin,
It looks like your injectors are installed 90* out.
The pins should line up across the TBI.
If you remove them you will see a very small roll pin on the bottom of each injector. That pin lines up with a small recess cast into the inside of the injector pod. I recommend installing the lower oring into the injector pod and not on the bottom of the injector. Then use some light grease or oil to lube the injector prior to install. That will help keep the oring from pinching or rolling.
I would also recommend checking the throttle shaft for play.
They can get worn and if there is too much play it may cause an unstable idle due to a vacuum leak.
I couldn't tell from the pics but if you have a flat throttle position sensor then there are felt dust seals that go on each end of the throttle shaft.They are under the pressed on caps.
If you have the round TPS then there are none and just a black plastic cap on the TPS end that the dust seal rides on between the TPS and the plastic cap.
