High idle usually means the idle screw on the front of the throttle is improperly adjusted and/or vacuum leaks in the intake. Leave the distributor for setting the timing.
Clean the grounds, check the wiring. |

remove the throttle cable from the intake connection and see if this still happens if so then you have a throttle body problem if it goes away then have a misrouted throttle cable

I know having a hugemongous vacuum leak will cause this. Specifically the Decel Valve hoses. I accidentaly pulled the Decel Valve while the engine was running and I thought the engine was going to blow up. It will be on the opposite side of the Throttle Lever on Throtle Body.
