Do you have a BOV? is it recirculated? is your IACV clean? check those basics out and we'll take it from there.

check the maf

Happened to me once. My timing was off a little and a vacuum line was cracked.

[J40sx]

Maybe dirty injectors, some sort of build up.

[steve shadows]

Yeah make sure your timing is not off 1 degree retarded.

+ re-cir your BOV or tighten it slightly

Also your throttle adjustment screw should be open enough and TPS voltage should be checked.

My friends car always stalls on him when he shifts into neutral, It's his BOV not being recirculated.

[huffandpuff00]

yup its cause of your BOV. Its an atmospheric BOV

[jdm styles]

ya i have a hks ssq and i will check all thoughs tomorrow thank u so much yay i hope it works

[2Slow40]

Probably your BOV.

I have the same one and its atmospheric. It only tries to stall if I'm accelerating or going fast then I put it in neutral.
Lesson? Don't race stop light to stop light.

[mifesto]

yeah hks ssq has a recirc kit for it....

[singlecamslam]

hks ssq BOV's should work fine without the kit, they should stay closed at idle. I have one and my car never stalls, it only stall because of my IACV.
