#1 ^ Please explain what you have in mind

#2 ^ Only tells you that you dont have a vac leak in your intake manifold however it wont tell you if you have a vac leak between the tb and the air sensor.

becouse the depressurization of his fuel lines means butkiss. Tmorgans idea of pressurizing the intake tract will actualy work. We allready established his FP was Dead anyway, so realy waiting until he swaps in the new unit is the best course of action for now. And someone has to step up and rag on the more experienced newbs. We cant limit the bashing or ration it ;)

Oh yeah and afm systems are as or more sensitive to vac leaks than most others the problem would either be a hose completely off or a failed hose venting at idle, becouse when there is a leak, the afm does not get enough flow to keep the trap door open. And this will shut off your fuel pump or lean you out depending on the severity of the leak.

wait so 20 is standard for vacuum? i sit around 24 at idle :dunno:

And I'm around 18. It depends on your tune as well as altitude. I'm at 7200ft.

hah makes sense I'm at 0......

Well the new fuel pump comes in tomorrow but i have to work the whole day so will swap it out wednesday and let you guys know if it fixed it. Will be picking up a new fuel filter today too while i'm at it.

any updates?
