Well, results of the new air intake are as expected. No change in idle speed. I did poke around the EHA, and did not smell gas. Also checked continuity of the throttle switch, (down low on the manifold), 3 prong guy that tells the CIS the throttle should be idling. Looked good. In reviewing the CIS portion of the CD Rom, I will need to hook up the multimeter and take some data before proceeding further. Thanks for the advice to date, I will update my progress.
