idle problems

[Hawker]

a couple months ago i gutted my EBPV. pulled the pin, butterfly out of the housing, and the piston out of the pedestal and plugged the holes. i even unplugged the plug on the pedestal.

I started the truck before leaving the shop tonight, and noticed about 2 minutes after, the idle jumped up to 1000 and stayed there.

If i touch any pedal, the idle will bump back down to the normal 650 or so. It doesn't do it all the time, but i've found that it does it more when it's cold.

any ideas?

I don't really know. I didn't think the 99's had high idle in them. My 2000 450 does, but it will only do it in P, not D.

its the high idle kicking in mine goes to 1000 rpms when i start it cold then hit the pedal it drop to about 700

yeah, but do the 99's have the high idle?

Thats normal. Takes a couple of minutes for my 02 F450 to high idle.

my early build 2000 has it

interesting. that's good to know.

Why did you gut it? Was it working ok or did you just want to clear the flow up? I think my EBPV is acting up, just thought I'd ask.

it stuck once on me, and rather than leave it, while i had the turbo off replacing the pedestal o-rings i just decided to get rid of it. didn't really take any extra time when the turbo was off.

My truck has a high idle it is normal I use it all the time I don't like running my truck until good and warm.
