You can't idle @14.7 most of the time with these injectors.
Start enrichening your idle and see if this continues.

seq inj and 14.7 and it holds no problem.

I'll try 14 or 13.5 just for the test.

Things I would try are :Turn off EGO, if it stops, i would change my EGO Settings, then enrichen the Idle with EGO off, or play with dead times(i think this is a small pulsewidths issue, tho)

Sorry, I never use this kind of injectors.
You should buy 4 new real injectors also bro, what's the point of risking your whole build on 89' junk?
