88 930 TURBO slant on way back from concours event in long island was occassionally stalling when going from one gear to another,....with clutch depressed it would stall around 2500 RPM'S ,would restart car and on a few more occasions did same thing from 1st to second gears.just took car out and tried at 2500 3000 3500 rpmsshifting into each gear and was fine...not stalled once. i was down b/w 1/4 and empty in gas on the way home and then refueled but certainly not at empty yet any advice? possible fuel inject issue?

 

I am by no means an expert, but I had similar symptoms, and it was a vacuum seal at the base of the IC neck/throttle body(after an Andial upgrade to the stcok 3.6 unit). I kep t having to replace an orange ring until I had a new neck faricated.
