To high idle or to not.

[TXFF]

Now that its getting cold I'm letting my truck warm up more in the mornings. Is it ok for the truck to high idle in the cold or is it bad for the truck? Second if its bad how can I stop the high idle beside sitting in my truck and holding the break?

the high idle you are refering to comes from the factory. i would not use the high idle mod mod on cold mornings as it brings the revs even higher. if you are worried about it, plug it in on a timer or just tap the brakes and it will bring it down for a few minutes.

Let it high idle. I don't believe in the high idle switches because you shouldn't be starting your truck in the winter, then immediately flipping the high idle or you have to walk out to your truck twice in the cold after it runs a few minutes to warm up a but then kick high idle on. But personally I let our trucks do it them selves. They know when to idle up automatically. It's not gonna hurt it idling up. It's supposed to do it. U dont have to hold the brake if ya want to turn it off. Just simply tap the brakes and it will go down to normal idle.

On cold mornings I use the standard high idle on the truck to let the truck get up to temp (many times the outside temp is -20). If Im just letting the truck idle when Im in and out of it I will engage my high idle switch to prevent wet stacking.

I don't really want it to high idle at all. How do I get ride of it all together.

It is programed into the stock computer from ford. The only way to get rid of it is if one of the tuners can turn it off through tuning, which Im not sure if they can or not.

why do you not want it to high idle? Do you want to tear up the engine?

How is not using high idle going to cause damage?

it's not about "using" the high idle... it's about trying to defeat the factory high idle during cold conditions.

There's a reason that high idle is written into the engine management! LOL

That makes sense, my truck doesn't idle up at all on its own lol.
