Car dies upon deceleration in neutral

[Luckybob2485]

If i am just cruising along, say 40 mph in 5th gear, and i push in the clutch, the rpms will drop and the car will die. It idles fine without any problems, and runs awesome, except for this one problem. I can keep the car from dying by constantly downshifting, and if i get below 20 mph and push in the clutch, it will not die. Is it possible that my atmospheric blow off valve is causing this? I have dsmlink, and ran a log, and everything looks to be good.

I am un sure if DSM Link can compensate that for sure or not. But Your BOV wouldn't be operational on decel, so its not like you are blowing off air that has already been metered. Could be your IAC(idle air control) not fully doing its job.

Thats what i thought as well for the bov, because it should be sealed if im not boosting.
