Idle Question
I couldnt find anything quick on a search similar to my question, so here goes.
I have a 2000 truck, and it runs great. Lately when idling, it for no aparrent reason will raise the idle to around 800-950rpm and hold it there until I blip the throttle, or touch the brake. Now I kow the newer trucks after idling for a while will raise the idle for a little bit and then back down, butmine has never done that. Its just got this weird issue and I dont like it revd up at almost 1k for half hour at a time whenever it feels like it; Thats why I bought the apcm idle controller.
Any insight on what could be the issue, maybe the throttle position, or something.

My truck will raise the idle, and stay raised until I either touch the brake or the accelerator.
Why dont my truck raise the idle, and then after whatever time, reduce back to normal idle.

I understand that feature, but I also thought my truck didnt have that feature. But my question and concern is that when it raises the idle, it is supposed to come back down after a short time or raised idle. My truck will not reduce the idle after any amount of time.

The AICs are just so you can have control over it, and kick it on and off with a flip of the switch. Say for instance you need to power something with your truck.... and it's summer time. You can either wait 30 minutes or an hour for the high idle to kick in, or you can flip a switch and have it instantly when you need it.

I understand the whole wetstacking thing, I understand why the truck does the idle thing. BUT, I only need to wait 5 min in 75 degree weather and my idle raises up. Thats why I was concerned somethign was wrong.
My idle controler was bought for the reason you said, so I can run a pto eventually, and I currently use it a lot for teh charge protect, when using my 12000lb winch. The ford apcm works flawless, I just get frusterated when the truck idles up by itself and NEVER comes back down. I thought that the idle raised only for a few min and then went down to normal idle for a while then raise again for a few min then normal idle; Not stay at 900rpm forever until you push the brake.
How is it supposed to work.

If the intake temp sensor is unplugged, or if it's reading the wrong temperature, then I could see it going into high idle too soon.
Yes, this is how it's supposed to work. But again, at the temps you are seeing, it shouldn't kick on after only 5 minutes of idle time.
