The engine computer uses a few criterior for what rpm to set the idle speed. Do you think a mechanical setting has changed? No adjustment procedure is given for the throttle valve because none is needed (and, it is illegal to change the factory setting). The throttle plate adjustment was good for 25 years.

Write the checks and findings in a notebook. Start, and perform each check completely…No jumping about. You saved me months ago with your diagnosis of my ignition coil. Would a cloggged converter cause idle to be soo high? Do you know where the idle screw is? Will I find it when I pull the throttle body? Thanks for answering. Any further info or ideas would be great. I have long suspected the converter they gave me was the wrong kind or just bad ever since they put it in - about 1 1/2 years ago.

Then I’m going to disconnect the exhaust pipe ahead of the cat converter and see how it changes things. I have been reading past posts of yours around this problem, so tomorrow I am going to do 2 things: Pull the throttle body to double check it and clean it (again) and as many hoses as I can find and blow them out just to be sure, even though the vaccuum check says all is fine as far as leaks. When your engine is “on the overrun,” like using engine braking down a steep hill at high RPM, you’ll see really high vacuum readings.” “When you floor the accelerator pedal, you can watch manifold pressure (another word for vacuum) swing from strongly negative to nearly zero (atmospheric pressure). Here’s a quote from one of your articles about my problem:

Yes, I know how to read a vaccuum guage and my Haynes Manual also contains the pictures and decriptions of the different readings. Hellokit!! My darling, where have you been.
