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!

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.

Ram 1500 throttle position sensor replacement
First i apologize for the awful camera angle/resolution for the first half.
I decided to make a video on how to do this so that way it would be easier
for people to do it themselves in the future.
My trucks symptoms that brought about this part replacement were whenever i
was coming to a stop, usually turning or hitting a bump while turning, the
engine would just shut off. all electrical was still working, stereo still
on all lights etc etc. alot of the forums i checked said it was either the
crankshaft position sensor or the throttle position sensor. so i did both
:( hope this helps anyone out there. I will update if this doesnt fix the
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.
For more information on diagnosing engine performance issues, check out
this article I wrote.

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.
1999 Dodge Ram 1500 5.9L idles rough.
My truck started to idle rough about a year and a half ago. There are times
where I would be at a stop light and it would idle rough and hiss.
Sometimes it would die on me. I thought it was a broken vacuum line or
maybe the thermostat (it doesn't overheat) but it could be the EGR valve or
something else. I am not a mechanic but I can replace parts on the engine
if needed. If anyone can help please post reply or video response. Thanks.
