Car dies after high rev?

[zrsnopro97]

Got a goofy problem with my car. If i rev the car up real high it dies instead of going back to idle. Also, say im cruising in third gear at over 2000 RPM and let off the gas and push the clutch in, it will also die if i dont get it into the next gear within a second or two.

Car idles fine if i dont rev it up.
My BOV is recirculated.
I have done a boost leak test before and i believe its all good.

Any help is appreciated
thanks

Bad/Stuck ISC, BISS needs adjustment?

I know when I have that issue, playing with the BISS fixes it.

Ive adjusted the BISS once before, but its possible its backed out due to the freakin poly motor mounts . Ill go ahead and check that this week. I read a write up on how to adjust the BISS before...do you really have to use a jumper wire and stuff, or can you just turn the screw?
