I just checked my IAC and that was pretty clean. I knew it was a Vacuum leak. I could hear it and it appears that my lower common chamber - intake manifold gasket is cracked. Looks like the gasket material is hard plastic-ish and has cracked. Might have hardened from heat ? Who knows. Well a quick fix was some of that silicon insta gasket stuff. I filled the cracks and I'll see tomorrow it that fixed it.
The trouble codes that I pulled from my Scan Gauge II was a 171 originally from the weekend trip and then I cleared them. Before I found the second leak a 171 came up again. Final time no codes came up.
