'95 T100 3.4 automatic.
Yesterday I pulled the intake snorkel from the throttle body and cleaned the gunk out that was on and around the throttle butterfly. Of course, I did it with the engine off. Quite a bit of crud too. Upon putting everything back together and starting the engine, my idle speed is now probably 1200 RPM according to the tach. The manual specifies 650-750 in park with the engine at operating temp. I've disconnected the battery in an effort to "reset" the engine computer since I thought that with the different airflow parameters after the cleaning that the computer would have to relearn data from the idle air control valve. So anyway, can I reasonably expect the idle speed to return to normal after a few days/miles of operation? Thanks for any knowledge you can send my way.
