The 5.9L engine runs but will not Idle.

Hi, I was unable to locate an EGR valve in any engine diagrams I ran across for your engine. However, if you know what an EGR valve looks like then trace all lines, tubing from your intake manifold. Sometimes they can be located at the back of an engine but more than likely they are at the front or the side of the engine usually with only one electrical connector and two screws that mount the EGR valve to an exhaust tube.

Hello Jeff Winner,

Over the last 20 years ... cars have has a LIMITED OPERATION FEATURE added... When the engine READS something that is not IMMEDIATELY catastrophic... it will allow you to
LIMP home... rather than a complete shut down.

Limp mode:
You SHOULD also have a CHECK ENGINE light... (?)

My best advice is to limp on down to your near-by FREE code reading shop... and have a READER tell you what CODES are registered...

A blocked exhaust system will also seriously SLOW your progress
((soon to stop all-together)).

Hope this helps

Check you exhaust prices BEFORE you go...!!

More info needed. Do the brake lights work? If yes, then there are 2 possibilities: The the flasher on/off switch is bad or the flasher unit is bad. A parts store might let you try a flasher unit to see. They can also tell you where the unit is, if you don't know. In small towns, parts stores are more flexible and cooperative.

There may be a fault code or codes stored, though. Have an engine scan done for trouble codes as a first step in diagnosis. If no codes are present, I would start by investigating the idle circuit-clean the throttle body and have the IAC (idle air control) tested for proper operation. Good luck.

Check for vacuum leaks, this is a common problem on the durango. Unmetered air enters the engine and creates a high idle condition.

either dead cell in battery or the idle air sensor or oxygen sensor going bad

if this is a 4.7l engine, the valve is on the left rear of the intake. loosen the 8mm bolts that hold the egr intake tube to the egr valve, remove the egr bolts, disconnect wiring, remove valve and tube together, attach intake tube loosely to new valve, install new valve, tighten tube bolts to egr using a swivel socket, this is not a 5 minute job, so dont attempt unless you have some time and patience.

Change fuel filter?

Common problem with these engines. Probably has a slight coolant leak at a head gasket causing this problem. Recommend to install reman engine you will save time and money compared to overhauling existing.
