what does it idle at ?

Chapman88SR5

does the idle bounce when your just sitting there with the brake is on? but if you let off the brake, it idles fine?

yelloyota

Both the idle goes up and down when the brake is on and goes faster when you apply the brake too, and it idle up and down when the brake isn't applied.

I don't have a tac to see what it idles at.

Search idle surge for more posts. Pretty common issue apparently and most likely not something that will wind up causing a premature truck sale ;>)

Thanks I just read it and will work on it in the morning.

Try checking the coolant level first. Top off if necessary.
