Full exhaust? Any problems with the O2 sensors? Any CEL showing up?

Did you mess with the MAF sensor or either of the two rubber vacuum lines that go from the valve cover to the intake mani or intake piping? I know when I did something wrong on both of those it would crank up the motor but it would shut it back down almost instanteously.

no its more like a kinda choking it stutters but doesnt cut off idle bounces from 500-800 and keeps going

What caused your vacuum leak? It may lead you to what is causing the idle issue. What all did you do to it/mess with when you did the full exhaust? That may help out some people that are trying to figure it out.

my vaccum leak was my coupler from the tb to the intake it was off....

Ok, so I'm taking it that you have a CAI. Did you make sure your maf sensor is plugged in fully. When my wasn't plugged in it bogged the engine down so it wouldn't go past like 3.5 or 4kish I think.
