My 89, 3.0l hits 2k right after start and does not change as it reaches normal operating temp. I have done everything I know to find a vacuum leak but nothing. I replaced the ICS, TPS and took the TB apart and cleaned it. I took the bottom off the TB and cleaned that as well. I did not see a wax anything. I did see a spring thing that the heater hose attaches to. So I figure that it is some sort of cold idle speed deal. Nothing I have done thus far has changed the 2k idle speed.

Should I see this wax or did my montero swallow it?
