We got done installing my F.C. manifold today but now the car will start and then just die. There is a loud hissing sound and the intake has backfired a couple of times but all of the vac. lines look good. It wont idle at all, and when keeping it at a steady rpm there is a weird gurgling sound in the exhaust. it sounds like its missing when holding the throttle constant and when reving it sounds normal???

Is the engine reving iteself? If you turn it on, does it start reving to save itself from stalling out?

What you look for is a change in engine speed (could be + or -) when the spray hits a vacuum leak and gets sucked into the intake manifold and then into the combustion chambers. Suggest using spray with one of those thin red nozzles so you can precisely direct the spray. Evin if you have to hold the throttle open a little to keep it running, this method should pinpoint the type of large leak that you have described. Good Luck.
