High idle
A beginner in most of this. I just put new plugs, wires, and distributer cap on this morning. Once I was done I fired it up. Since I got it, it always had a really slow turnover. Still had a slow turnover but when it fired it was idling at around 2300 rpm, it did go down a bit to 2000 but wtf! What did I do wrong?

Re: High idle
You posted in the wrong section, Sounds like a vacuum leak. The slow cranking could be to far advanced timing, weak battery or starter or cable corrosion or connection.
Re: High idle
Its the right section.
On TP's advice though, that'd the best place to start. Follow all vacuum lines and look for cracks and/or breaks in the lines. Check timing with a timing light, make sure to mark the dampener. Check the grounds on the battery and starter. Most importantly, make sure you have the correct battery for your application. A quality battery like a Optima Red Top is a great upgrade.
