My question is I have a 1996 Isuzu Rodeo and when I start the truck the Idle is high and then I turn it off and then start it again and its ok, but once I start driving it and get to a red light its start idleing high again. Tonight it would not stop, I drove for 20 minutes and still not stopping. Not sure what is going on with this. When I get to the red light is like the truck wants to keep going. I hope you can help me cause I am at a lose here. with this.

Try cleaning out the idle air control valve and see what happens

Check the radiator coolant level. Low coolant level could cause that as well.

Clean the IAC but before starting it unhook your battery for a little while it will reset and recalibrate it all. It fixed mine ( 1998 Isuzu rodeo 3.2 )
