Kyle,
Before spending any money on sensors, take off the TB and clean it. Make
sure you clean the IAT sensor and where it seats. Let me know how it runs
afterward.

Subject: DML: Rough Cold Idle/Coolant Sensor
First, what could/would cause my truck to run rough, only on cold start-ups?
Once the truck warms up and is started things are fine, and it doesn't idle
like I have a 440 under the hood with a wild & nasty cam stuck in it. My
truck has done this for a while now, and even though it doesn't bother be
'that' much, I still would like to fix it. I am leaning towards the coolant
sensor, which is about $15 or so.
Has anyone ever replaced this coolant sensor on their Dakota? My
understanding is that there are 2 types:
*One is located close to the thermostat on the manifold which sends the
computer how warm/cold/hot the coolant actually is. Could false readings or
a bad sensor could cause a rough idle at start ups(both cold and warm
startups)?
*The other is used for the temp gauge on the dash. This would obviously
cause a poor or inaccurate reading on the temp gauge on the dash. Where is
this one located?
I have read alot online concerning the coolant sensor and have found a bad
coolant sensor has the potential to cause excessive fuel consumption, poor
cold idle, and even stalling. Like I stated in the beginning, the cold start
ups are nasty and rough, and there are NO fault codes coming up when I do
the key on/off cycle. Oxygen sensor was replaced about 23,000 miles ago; the
cold idle problem did not change and was present beforehand. Any ideas?
