I have asked this question before and the answer that I got was a vacuum leak. My car has a high idle all the time like 2000+ rpm all the time and its pretty much steady. Just wondering where to start to find the vacuum leak if that is what is doing it? I looked at the linkage it all seems to be free and not binding.
Any thoughts on where I should start to troubleshoot?
Check all the hoses & lines attached to the intake manifold as far as they go for cracks & rusted holes etc. Some people use an unlit propane or acetylene torch to supply gas along the hoses & lines. If the rpm increases, there's a leak there.
Pretty sure it was, I was out by the door with the rain and wind. When I took my finger off it increased and when I put it back it decreased. It still never went down below 1200 to 1500 RPM's. I am going to double check again the weekend.
Maybe a stupid question does the engine have to be warm or does it make a difference?
Update. I went over all hoses again with propane and no change to the RPM's, RPM's steady around 1200. Idling pretty smooth and too me it didn't seem like it wasn't idling high. I remembered that I had one of those EQUUS vacuum tester and RPM gauge/voltmeter. I hooked up the vacuum tester and the vacuum is solid on the normal and the RPM's that is showing on the gauge is around 950. So that leads me to believe that my tach is not accurate.
