96 Tracker runs like crap

[fixkick]

not saying it is same but very close
if you can nab one for free, post if it works.
it looks the same if 1.6L
id say if the diaphragm seem same diameter. it may be same.
there are some orifices that matter that can not be seen.

id say off hand only "B:" diaphragm matters, diameter, the bigger engines uses smaller diaphram.
all else there is huge. in sizes, red line only thing that may cause changes. the red line is filtered air, at atmospheric pressure, 1bar.
the bark pulse makes this beast flutter inside, such that the more BARK pressure you get the longer you get vacuum from Q to P
keep in mind it is only 1 (#4)( cylinder pressure so engine size is 1/4 or 400CC engine exhaust pulses, a very odd system here.
good luck with EGR.
