97 Tracker - Poor Idle, Hesitation

[fixkick]

seems this is common now...
all that is true
the diaphragm dead will make the acceleration weak, due to lack of rising fuel pressure to match need (vacuum drop)
hope it solves all issues, for sure some...

happy trails

the trim is complex , it may store say 16 trims , (diff,loads./rpm)
and will be trying to correct the errors, and cant , correctly with this form of chaos,
the trim corrects and no sooner corrected ,its wrong....
