whats the code ? should tell you which one it is,,, also as far as the vacuum leak goes just gonna have to inspect all the vacuum hoses for cracks spilts and that they are all connected and tight like the should be,, can use some starting fluid but don't spray too much but your idle should change when you spray it on a line that is leaking,, can also do that to find the intake leak as well,, the IACV you just put a new one in,, should be on the front of the throttle body,, the dirty throttle body can be cleaned up by taking some brake clean and a rag and cleaning up the intake by hand
