i just bought my first stang, a 95 gt, when i first start it, it will idle at about 600-800, then if i rev it at an idle it will drop to about 400- or 500 and sound like it wants to stall, it also hesitates while driving, i had it checked out on a computer, it showed that the o2sensors were to low, but the mechanic said i had a vacuum leak, i took the advice of everyone on this page and replaced all of the rubber boots on the vacuum lines, and sealed them with silicon, still does it, i changed the plugs and wires yesterday, and it still does it, im really stumped here, could it be the o2sensors? if it is i can get them cheap, but do you need a special tool to get them off?

i changed the fuel filter to, right now im putting all new plug ends on the vacuum lines, and i cleaned the throttle body, still starvin for fuel

Wouldn't hurt to change the O2 sensors, though I don't think that's your problem. Check to make sure all the grounds are connected. Check fuel pressure with a gauge. Check IAC (on throttle body).

Clean your MAF. Take it apart, clean the points with alcohol. Make sure not to get anything wet thats not supposed to be.

Peace

The little cylinder shaped thing on the throttle body, has a clip with a wire attached to the end
