1999 Dodge Ram 1500 all fixed. Here was the problem
I fixed the problem. It was the IAC (Idle Air Controller)
I'm sorry that the video is not more detailed but fixing it is not hard. A
few screws and a plug and some common sense on how it all comes apart and
is put back together.
I got a lot of emails and comments asking what the problem was so here is a
video pointing it out. I hope that it helps you.
1999 Dodge ram plenum repair
Fixing the plenum pan on my truck... its a common problem on 2nd gen dodge
rams. When the gasket blows it lets oil into the intake which gets sucked
into the cylinders... most trucks mine included were just re programed to
run diffrent instead of dodge fixing the plenum. After replacing my plenum
pan and intake gaskets, i have more power and it hasnt used any oil or
coolant in the past week.
3.9 v6 Magnum IAC rough idle
My 3.9 v6 Magnum was idling rough so I cleaned the throttle body and intake
along with the IAC which was very dirty. Put it all back together and she
runs very smooth!! It would idle high then low when in park or neutral, and
almost stalls in reverse. But that cured it. Be carefull not to pull or
push or twist the probe or you will have to buy another IAC. Hope this
helps some Dodge fans out there!! make sure to clean in the IAC passage!
Thanks for watching!
Idle Air Control Valve (IAC) 2002 Dodge Dakota 3.9 Stalling
Stalling in low idle conditions, shifting from forward to reverse or from
park to drive, etc. is typically caused by the IAC. Replacing it is fairly
This is one of those conditions that the on board diagnostics (the engine
light) or an OBD reader does no usually detect (because it typically only
detects a complete failure condition and not intermittent problems)
How to clean a throttle body and Idle air control valve (iac)
*** PLEASE READ ***
In this video demonstration, I show how to get to, remove, clean, and
replace the throttle body and idle air control motor (aka IAC) on a 4.2l
ford motor. This procedure is the same for any fuel injected vehicle.

The vans require removal of alot more stuff just to access the throttle
A dirty IAC can cause a rough idle. A dirty throttle body can harm
performance and cause rough engine operation.
When the throttle body or iac is removed a new gasket must be used to
properly seal the connection to the intake.
GM idle air motors are generally mounted on the throttle body and can be
cleaned without removal from the throttle body. This means one less gasket
and a lesser chance of creating a vacuum leak.
The ford throttle body had a note on it that said it was not to be cleaned
because the coating on the throttle blade might be damaged. Thats fine for
a new car but that has to be disregarded when working on something that has
some miles on it.

Jeep IAC idle Problem - Before and after cleaning the IAC Valve
This video shows the idle problem that came along this week. It started
with some revving on its own one day, in park when I put it from drive to
park. Then it began to get a rough idle. Not maintaining rpm when releasing
the throttle, and so on. The rpm would also be unsteady in park/neutral.
When putting it in drive/neutral the engine would stumble and drop to 0 rpm
just to wake up half a second later and maintaining normal idle.
What I did was take out the IAC valve and soak it with 5-56 (a solution in
Sweden similar to WD-40)
Then pushing in the pin and pulling it out several times. Drying it off,
scraping off all the black deposits and putting it back in. Then the Jeep
noticed a difference and I noticed a different throttle response. After
driving about 2 miles in 45mph, letting it sit over night. Starting it and
driving it in the following day was a dream. A completely different
smoother running engine and a very much more responsive throttle.
And of course, it keeps a steady idle now.

How To Find A Vacuum Leak - EricTheCarGuy
Vacuum leaks are one of the biggest causes of engine performance problems.
This video is pretty straight forward in it's approach to finding a vacuum
leak. On thing I might mention is that not all vacuum leaks are at the
engine. Some HVAC systems run on engine vacuum and can cause a leak under
the dash in some cases. I've even seen vacuum operated door locks. Just be
sure to be careful spraying flammable stuff on a hot engine, you don't want
to take one problem and make it a whole lot worse. You can also use a spray
bottle with water to do this same test. It may not be as effective, but you
don't have to worry about spraying a flammable substance on a hot engine.

this article I wrote.
