why doesn't my hi-idle engage??

[85_305]

I've noticed my truck never kicks into hi idle. No codes or lights

[KeepinItFord]

Hi Idle? why would it?

[85_305]

Because after like 2 mins or 5 mins it's supposed to go into hi idle to keep ac/heat working optimally and to prevent wet stacking.

It should only barely idle up....not like a hi-idle on a chip.

my truck idles itself up alot when its cold out but thats the only time iv noticed

[85_305]

My truck doesn't even idle hi on warm up.

But i'm telling you the needle does NOT move at all.. no matter how long its been idling.

i wouldn worry bout it unless it cold out like 45 degrees or less

That's when mine does it....usually only in the winter. Had a low of about 50* last night. Didn't do it this morning.

So under 50* at LEAST then... I heard they are supposed to it all the time.

how come my idle doesn't come up when it's cold to warm it up quicker?

you have to get it on a custom chip as one of your settings
