so i was talking to someone who works on some busses with the ctd engine in them and he was saying that he was suprised that i dont have a "fast idle switch"??? is this something that diesels should have? can i buy one if it should have it?

I've been trying to find someone with a Bully TripleDog to program mine... to work with the cruise control...NO LUCK ! and My automatic fast idle stopped working

Find some one that has a smarty and you just for trying it will have the high idle downloaded FREE

I have also seen where people will use high idle solenoids off of old quadrajet carbs to trigger the high idle.. Maybe this is what your friend was talking about

Here's a repost of mine from a while back for someone else; may be relevant here:

There are high idle boxes out there; you can probably get them at most any diesel shop. I never did much checking into it, but I think they run about $170.00-$400.00. For a much less expensive alternative, if you're able and willing to get into a project involving work with electronics, here's some (read: a LOT of) interesting reading:

That's where I got ideas to base the high idler in my signature on. All told I spent less than $100.00 to build it, including the plugs to connect it to the APPS and factory harness so I didn't have to do any cutting or splicing on the factory wiring. If you need more info I'll try to dig it up for you.

I will run out of shovel handles, broom handles and all other sticks in my entire neighborhood (that can be used to prop the gas pedal), before I buy a $400 high idle box.

I too used tose instructions to build a high idler. I have lots of pics ad schematics with labled pins if you need them. Let me know

I KNOW YOUR RIGHT !!! some people just have too much $$$

My high idle is a cut closet rod...whe I want a higher idle...I move the seat forward. Runs about $2...It hasn't broken yet!

hahaha ok cool. im a newb with diesels and i didnt even know what high idle was or why it needs it(i still dont) but when should i be doing the fast idle prop??

A higher idle, when idling for an extended period of time, helps prevent wet stacking. It keeps the cylinder temps hot enough to burn the diesel fuel completely. Wet stacking occurs when the fuel does not burn completely and washes down the cylinder walls. Another effect is deposits can form on the back side of the exhaust valves, which can cause the valves not to close all the way. This can result in the piston giving the exhaust valve a love tap. High idling in the colder months helps warm up the truck faster, and helps the A/C work to its full potential in warmer months.

Well I'm interested. Can you please post your schematics and pics, in the mean time I'll start reading the old post. Thanks in advance.

I won't spend $400 on a high idle box either, maybe not even $100, but if I can make one for $20-30, I think it sure beats a stick.

I uploaded the photo, but it has to be approved first. As soon as it is I will post the pic here. I made a few changes to mine to get it to work, and they are reflected in my diagram.

Go down to your local truck parts store and pick up a twist **** High idle throttle lock. Cost about 25 bucks.
