Thunk! Stall! Hiss!
ok here is the deal.
My car (81 GSL) will start and run for a few seconds then you hear a "thunk" (hollow sound kinda like a tennis ball cannon, but softer) then the car stalls.
Once the car stalls you can hear a hissing from near the drivers side of the engine bay but I cannot pin point the hissing, any ideas folks? cause this is pissing me off.

Thet thunk is probably a misfire after the car dies. For awhile my car would do taht same. I would shut it off and a few seconds later I hear that thunk sound, like you describe it.
As for the hissing sound...dunno really.

dunno the thunk sounds waaaaay too soft to be a backfire. I a standing looking into the engine bay as my wife starts it. It may be a tiny backfire but highly doubtful. It sounds like somebody dropped a wrapping paper tube...bout that loud
