Idling

[Banshee34]

I have heard many different theories on idling too long can be harmful, etc...

Anyone have any thoughts?

[Gear Jammer]

I think it can be to harmful. I drive 18wheelers and i was allways told if your going to idle for more then 10mins to Idle them up higher. If you ever go in trucks stops there trucks are never at an idle. there allways set at alittle bit higher rpm's. There has to be a reason behind this i would guess.

I've always heard it can cause wet stacking, that's why I did the high idle mod on mine. If I'm letting her idle for any extended period I just flip the switch and she idles up.

Ok had to warm up the truck for about 10 minutes this morning... when I came out to leave it was running at 1000 rpm... I touched the brake and it dropped..... So is that idling at an acceptable non-harmful rpm?

High Idle mod?? More information please.

[SRDIESELSCOTT]

Idling at 1000 RPM's is ideal.Most major engine builders in the class 8 class tell you to idle up to 1000 RPM's when sitting for any period of time.Ford has an idle up programmed stock for cold weather running and it does go back to normal idle when you push the brake pedal.

Great info!!!!! Just have to figure out the 7.3 now. I'll look into it this weekend when I'll have daylight to help me.

[purduefarmboy460]

you get it figured out for the 7.3, let us know!

[F-350MAN]

you guys are talking about higher idle, I did the 10k mod on my 7.3 and it now idles at about 900 rpms all the time even when applying the brake but it does drop in nuetral or park

[f250powerstrokeman]

letting a diesel idle to long is not a good thing it lets carbon build up on the pistons and also makes the engine run cold which makes the piston rings wear out i am pretty sure that all powerstrokes 99 and later have the program from the factory which will make them idle 900 to 1200 rpms depending on ambient temperature outside and also has the exhaust back pressure valve helping it keep warm(tap the brake pedal this will also disable that also) when u tap the brake pedal it will drop back own to normal idling rpms
