Default Re: 99 3.0 5 speed ranger has just started idling 500 RPM's higher than normal!

Sounds like the regulator is off.

The engine has to work harder with weight on it so fewer rpms, if you take the wieght off it should spool up and go faster. However, i believe this is regulated by the computer these days. So I would start there.

A 99 should have a computer, but if for some reason it doesn't (I don't know how or if they regulated this before computers but if they did figure out what part that would be and if your truck has that part check it out and see if it needs to be replaced.)
