to jmatzick:
I'm not really an expert but I believe short of hearing the leak(hissing) using aersol carb cleanear or starting fluid is the second best way to identify unmetered air getting to the engine. I had a Toyota with a leaking intake manifold gasket and I used carb cleaner to repeatedly smooth out a rough idle. I'm thinking I could spray around the base of the UIM/LIM and if the idle changed a loose or leaky gasket/seal would be suspect
to Rogerm60:
I'm going to order the part for the UIM & LIM intake rebuild. From your description doing this first will probably solve my problem. Regarding EGR build up, is it necessary to remove and clean or replace the EGR valve or other emission components once I have the intake system off the car. Any thoughts? I'm not looking for trouble but I only want to do this once. If it's not a big deal to do EGR stuff after I've done the intake rebuild I'll tackle it when the need arises.
Once again thanks for your reponses.
