Ok...my cars idle is jumping....when i drive it has even shut off.. i have to push on let go of the peddle just to get it to run.. if i press too hard i get a vrmm vrmm vrmm.. real loud.. i changed my throttle body and sensor, maf sensor, checked my injectors, checked the fuel filter, spark plugs and wires.. then i decided that i would take it to for.. and on the way to ford my cel went off.. so when i ot there they ran some test and came up with nothing.. WTF.. before i murdered everyone there i just decided that id come to ceg and see if i could get this figured out..

IT's a possibility that it's a vaccum leak.. but i can't find it.. to be truthful i don't know where to look i can hear a whiss..sound and feel a little air " i think" could be my imagination but i know where my brake line connects to the intake side.. i can move that little hose and i can hear the air.. i dunno if thats not on there tight enough or could that little leak right there be the cause.. i dunno what to do .!!!!

You definitely do not want to hear an air 'hiss' of any kind from any of the vacuum lines. I would fix this leak, and hope that's the only problem. A vacuum leak can certainly cause erratic, rough idling.

I agree, you most deffinately want that hissing check out, because I ended up spending some chedder. Let alone if its is a vacuum leak therefore won't belong on powerloss.
