the vaccum diagram should be located under the hood of your vehicle

They probably had your air filter out, 1st check the intake tube & vacume lines on the air cleaner box & intake tube. Make sure the clamps are tight & all vacume lines are on

High idle is usually caused by a vacume leak. First place to check is the cold air intake manifold. All hoses, throttle body, and sensors. Throttle Position(TPS), Mass Airflow(MAS), Idle Air Control Motor (valve) IAC. Controls Idle speed

A malfunctioning throttle system can cause both a high idle as well as an engine stall.

A dirty air intake or cracked air intake tube is often the culprit.

How to Fix an Engine High Idle in Under 15 Minutes

Find your vacum leak. It is sucking in to much air.

Try cleaning out the IAC (idle air control) valve. Located behind the throttle body on the B18c engines. Like the TPS it can get dirty and fails to meter air intake properly, giving the symptoms of a vacuum leak.

Hope this helps!

helm inc if you can't get them for free

sounds like you have a vacum leak in one of the vacum lines or you need to change the idle air control valve. start the engine and raise the hood and lisen for a vacum leak and check all vacum lines for dryrot. if no vacum leak can be found then replace the idle air control valve, this controls your idling

Common problem with Dodge Rams. Nobody has the right parts (dealer only) the right part numbers, or the right diagrams or component lists or locations.
The 5.9 L most likely has no EGR valve, as mine does not. It does however have an Idle Air Control Valve located at the back bottom of the throttle body, which if removed, will show carbon buildup, preventing proper fuel/air mix.
You also may have a vacum leak at one or more vacum hoses on the intake manifold, a leak at the vacum ball that stores vacum for working the vent controls when the engine is off. It looks like a big black ball, and has a vacum line going from the top of the intake to the ball, maybe located behind the RH pass headlight. The rubber hoses dry oput, crack, and rot after a few years due to OZONE exposure from the air. Go ot and buy 6 or 8 feet od 3/32 rubber vacum hose, and replace everything that is suspect. Look for cracked Ts. Dont forget to check the larger vacum hoses that go to the charcoal canister and fuel tank vent valves. The rubber elbows have a tendency to pop off the charcoal canister connectors on a hot day if you overfill the gas tank, and the rubber elbows are old and stretched out.
God Luck.
