 Subject: 2001 dak w/3.9 5spd Man. warmup Idle
IP: Logged
Message:
I have an Idle problem. I just got the truck with 27K miles and its winter in Minnesota so here is my problem.
If I start the truck cold and don't warm it up before driving away the idle speed when I up/down shift gears is just fine.
if I start the truck cold and let it warmup for a few minutes then when I shift to the next gears the Idle speed races and there is a roaring noice from the engine. This problem continues with each up and down shift until the engine reaches normal operating temperature.
What is causing this?

The roaring noise is probably the cooling fan
The high idle is a little strange you may have a
sensor that is a little off, IAT or engine temp
reading cold will cause the IAC to open to prevent
the truck from stalling while shifting.
My truck does that if I roll backwards and pop it
in nutral while I am rolling cold it will rev to
12 1500 when the truck stops rolling it idles down
Than I pop it in Drive and go they are weird
computer controlled vehicles do strange things
