I just bought a 1992 toyota 4x4 ext cab sr5 5 speed. When i first started the truck the idle was sitting about 1600. I figured that it was just because it was cold. Well after driving for about 20 min the truck warmed up and the idle seemed to even out at 1000. Then as i come to a stop the idle will jump back up to 1600 with the truck in "N" and my foot off the gas. Then as i start driving again it would drop and act fine. The truck keeps doing this and i am not sure why. Any answers will help. I have not checked for any vac leaks or sensors. This is my first 3.0 and i am not super smart about this engine. I am not even sure where all the sensors or common vac leaks might be. Please HELP
