One fairly simple thing to do early in the troubleshooting sequence is to carefully check for vacuum leaks. Look for disconnected or split vacuum hoses, intake manifold gasket leaks, injector seal leaks. You can use a hose as a stethescope to probe around the idling engine t l isten for the tell-tale hiss of a leak. Many suggest spraying carburettor cleaner at the site of a suspected leak. It the engine speeds up, the leak is confirmed.

Don't forget that the heater controls are vacuum operated and there is the potential for a leal in that system. Try plugging the vacuum line ot the heater to check. The brake booster is another possibility.
