vacuum leak?
I must have a vacuum leak somewhere. I can't get the idle to go below 1000. The car will idle okay, , it reads 1000, put it in reverse, stalls. When you get it going, it will stumble, then take off and run fine. When you come to a complete stop, it just dies. Start it up, idles fine at 1000 rpms, take off, then stumbles and goes through the same pattern. I checked all the lines, no leaks. Could it be the exhaust manifold gasket? the reason I say this is that when this problem started, the exhaust sounded different than normal, louder and rough. Any suggestions?

It could be the INTAKE manifold, but not the exhaust manifold. Keep looking, you have a leak somewhere. Check the hose that comes out of the back of the intake manifold. It is a common leak point.
You can take a bottle of propane/torch and use it to find your leak. When you get near/on the leak the idle will increase. Or use a spray bottle with some soapy water in it.

Well, check visually at the manifold, and if it's not there, compress (carefully!) the hose with vise grips or a suitable clamp.

I had the same problem with mine, and changed out the hose to the booster. Now I understand that there is a check valve in the hose that I should have saved! Now I need to find another one. Anyone know of an after market check valve that will fit the hose to the brake booster? Thanks.
