How do you find a vacuum leak in a 1995 dodge neon?

Find an empty spray bottle and fill it with soappy water (more soappy than watery). Start engine let it warm ( 5 min is good ). First try finding the area you believe the leak is occurring with your ears, and spray directly there. If engine rpm steadys, there she blows (Smile). Caution! There may be more than one leak, so move around the vacuum hoses slowly and carefully. GOOD LUCK.
