Stopping Startup Revving

How would I go about stopping the start up revving of the engine when the engine is cold?

Like say in the morning, you go to start your truck, it will idle at 1000-1200 rpms for like 2 or 3 minutes or longer depending on how cold it is.

I find this very annoying because I do a lot of stuff around my house, and I need a slow crawl ratio, and when the engine is revving, it's impossible to go slow, and I can't see waiting 3 minutes for the engine to warm up, because it is a waste of gas.

My Dakota will start up and go right down to 650 to 700 rpms even on the coldest of days. I'm talking instantly. I could start the truck, and with in 10 seconds, it's down to normal idle. Making it nice to work with during the summer around the yard.

When my F150 goes to normal idle, it's great, just like driving the Dakota.

It's just so annoying, and I've been dealing with it for so long on my F150 and I'm just tired of it.

Huh?

Anyway...

Two-to-three minutes seems unusually long.

We don't have extroadinary cold winters here [I've seen single digit once with WC factor many years ago] but on the coldest days/nights, my truck with idle at high revs for no longer than 60 seconds.

To answer your question though, you'd have to tamper with the electronic choke. The rest is out of my league...

Well... like 2 or 3 minutes when it's really cold out.

But during the summer it only lasts about 60 seconds. But it's still quite annoying to have to wait.

WOW some people its on high idle to get the engine lubricated and up to operating temperature. it does it longer in the winter because its cold out obviously, shouldn't jump in any vehicle that isnt "warmed up" and drive away anyway, but some people dont care about engine wear. a waste of gas if that worries you, guess you shouldnt be driving a pickup. mine has idled for several minutes when it has been damn cold (-30+ ) it really isnt that "high " of idle anyway, 1200 rpm aint nothing to get excited about. i'd just sell that f150 and keep driving the dakota, its seems that truck is perfect, another flop by dodge.

I don't really get what you mean by "I do a lot of stuff around my house" or why a slow crawl is so important, but if your truck is a manual, have you ever just pushed the clutch in?

I'm very confused as to why this is an issue....

for the record, I never warm vehicles up. it is a waste of gas. As soon as I can see out the windshield on a frosty day, I'm rollin. I take it easy until it's warmed up, but I never let it just sit idling for 5 or 10 minutes to got hot.

On cold mornings on my way to work at 0610Hrs., when I start up my truck & goes to high idle, I use that time to tune in Howard Stern on the Sirius Satelight radio, & adjust the temp controls. To just get into a vehicle & drive away before letting the lubricating Fluids circulate will just take useful miles away from the lifespan of your engine! Question, When you get out of bed on a cold morning, do you just sprint a 440 yard dash.......? No, I didn't think so! If you don't like it, your engine doesn't either!.............

I agree that 2-3 minutes is a little long. Even in below 0 temps mine idles down after no more than 45 seconds.

Here's what you can do: pull out the PCM, remove the throttle body, and replace with a carburetor. Sorry Manual but this is a silly question. There's nothing that can be done to change it, besides the higher idle is needed to get the converters up to temp so they start working. After about 30 seconds to a minute it should be down under 1000 RPM and ready to drive.

Oh, I'm really careful... I feather the heck out of the clutch... but I feel like I'm reducing the clutch life a little bit more by being anxious.

I think there is no way around it.. just gonna have to live with it. I thought maybe someone knew how to change the PCM settings using a tuner or something, so it would justify me buying a tuner rather than just for performance reasons.

But thanks everyone!

According the owners manual you should never let your truck idle more than 10 minutes. I guess Ford will void your warranty.

It helps light the converters off faster. You can wait three minutes or whatever.

Yet you're complaining about 2-3 mins.

Go figure...

If you set all the adders to 0 and the multipliers to 1 you can essentially remove what you want, but it may stall on startup.

I used to sleep in my '99 because I could unfold the rear seat... and I got some nice blankets and pillows, and made myself a nice bed. What's awesome was that I am short, so I can lay down like I was actually in a regular bed too.

I can still do the same thing my '07 ... just fold up the armrest, and get a blanket with 2 pillows and I'm set.
