cylinders 5 and 6 are dead
i have a 89 3.o v6 and i am having problems getting it to run on all six cylinders. i have 150psi of compression,good spark,and good injector pulse. i swaped 5and 6 injectors with 1 and 2 to see if the problem would follow it did not. when it runs for a bit you can pull the plugs out of 5 and 6 cyl. and they are black with carbon. i am stumped not sure how to get 5 and 6 back firing.

Check for spark on plugs 5 & 6.
You've ruled out injectors & have good (if low) compression, so it's got to be spark related.
Was compression check with engine warm, all spark plugs out, wide open throttle, & VAFM disconnected per the FSM?

How did you check for spark? Did you look at it or did you use something like this?
