Driveabililty Issue

Seems As if my car wants to stall out on me while it's slowing down...

As while I am just coming to a stop, and the car is still in gear it seems to be having a hard time coming back down...

And once I hit the clutch, the car's rpms drop and occasionally they drop too far and it stalls out

Has had the IAC replaced a good while ago..
Just got a new MAF sensor for it as well...

PI intake/bbk throttle body/plenum

Did you try raising the idle?

Use the screw on the TB...loosen it up a turn or so and raise the idle a bit.

Not yet... But the car doesn't want to die while at an idle... After it warms up some the idle bounces but never enough to where it stalls... It just seems once I hit the clutch the rpms drop too fast and gets too low..

Oh, and it also seems to be running a little rich, just from the smell... Even though I do have an o/r x and LM1's, the smell is worse than it has been before..

The car also has a small puff of smoke on some start ups... Not sure what color it is, but it smells...

vacuum leak? or maybe something going haywire with your vacuum on your brakes. ive heard if we (sn95 drivers) slam on the brakes too hard it will stall out the car, because the brakes are run off vacuum for assistance (or something like that... perhaps someone else can clearify what im terribly regurgitating from another mustang owner.)

Yeah, I'm going to have to check it this weekend unfortunately... Probably run a can of seafoam through the thing...

But first, I'm working on getting my speedometer working. I hate my toys. :BangHead: :BangHead:
