No wideband? No HPTuners? No idea what occurs when this happens besides that it "dies when you come to a stop."
Does it die as you roll down to 0? Does it die once you stop completely? Do the RPMs hunt around before coming to a rest at 0 RPM? Does the car turn off electronically as well as mechanically (as if you turn the key to OFF)?
With limited info provided, you will never get an answer.

ur right i should have explained a lil more...im tired and forgetful...
ok anyways...its dies as if im off the gas and in neutral...like if im slowing down with the clutch out and just hitting the brakes (which i know i shouldnt be doing) and once it gets to idle it will drop down to about 500 rpm and then die....
and if im doing 45 just cruising with traffic, take the car out of gear, and dont hit anything it dies...its being intermittent at the moment and i wanna stop it before it burns up the turbo....i really dont have money to get a new one yet...
now if i turn the ac on it will hold it but after a lil driving the problem comes back...
as of right now i dont have HP tuners or a tune at all..i just got the car so i am soon to get one when i can find someone to do it...
i am waiting for the wideband to come in...its shipping as we speak....
and the car starts right up after it happens...and all the guages and lights and all work after it dies...only code im getting is for the cat since there isnt one...

Check your idle air control valve it could be malfuctioning I've seen them go bad multiple times without throwing a code. If its stuck closed it could kill the car when come down to idle.
ok...sounds like it could be the issue.....
any chance u would happen to have a pic of where it is so i can make sure im checking the right thing...lol

I'm assuming you have a larger non factory exhaust (2 1/2"?) without a heated o2 sensor. if that's the case, wait for the wideband and wire it up so it is used as a wideband AND narrow band (replacing your pre-cat o2 sensor) and you should be ok.
hey buddy my car wasnt turbo and i was having the same problem then it went away for like 3 days and then it left me dead on the highway come to find out it was my fuel pump went out. dont know if thats your problem but hope it helps
well i havent had an issue for a day or 2 now...its got a high flow pump and i hear it kicking on so i dont think that waws the issue.....maybe it was just some bad gas....i did stray from my normal chevron premium and if im not mistaken thats when it started...so i think shes good now...key word being think...we will see how things go in the next couple days...thanks for the help everyone...
