Is Your 2004 Durango Running Rough? It Could Be The Engine Computer.
The 2004 Dodge Durango, especially with the dependable 4.7L V8 engine, is a workhorse. However, after years of service, its electronic brain—the Engine Control Module (ECM)—can begin to fail. This can lead to a host of frustrating and often misdiagnosed problems, leaving you stranded or dealing with a vehicle that just doesn’t perform like it used to. If you’re experiencing perplexing issues that other repairs haven’t fixed, it’s time to consider the central command unit. A failing ECM can disrupt everything from fuel delivery and spark timing to transmission shifting, making an accurate diagnosis difficult for even seasoned mechanics.
From the Diagnostic Bay
We had a 2004 Durango 4.7L come into the shop that was driving the owner crazy. It had a persistent random misfire and would occasionally stall at red lights. The owner had already replaced the spark plugs, ignition coils, and even the crankshaft position sensor, but the problem remained. After hooking up our advanced scanner, we noticed erratic data from multiple sensors and intermittent communication loss with the module. This pointed directly to an internal fault in the ECM. Instead of chasing phantom sensor issues, we replaced the engine computer. The Durango immediately ran smoothly, the stalling disappeared, and all engine parameters returned to normal. It’s a classic case of symptoms pointing elsewhere when the root cause is the computer itself.
Common Symptoms of a Failing 2004 Durango ECM
- ✔ Check Engine Light: An illuminated check engine light with codes that are inconsistent or point to multiple sensor failures (e.g., U-series communication codes, P0601 internal memory error).
- ✔ Engine Performance Issues: Noticeable loss of power, poor acceleration, and a significant drop in fuel economy.
- ✔ Stalling or Rough Idle: The engine may stall unexpectedly while driving or at a stop. A rough, erratic idle is also a very common symptom.
- ✔ Starting Problems: The vehicle may crank but refuse to start, or it may take multiple attempts to get the engine to turn over.
- ✔ Misfires: Persistent engine misfires that are not resolved by replacing spark plugs, coils, or fuel injectors.
- ✔ Transmission Problems: Harsh or erratic shifting, as the ECM plays a critical role in communicating with the transmission control module (TCM).

Will this fix my check engine light?
If the ECM is the root cause of the fault codes, then yes, this replacement will resolve the issue. After installation, it is important to use a scan tool to clear any stored fault codes from the vehicle’s memory to turn off the light.
Is installation difficult?
Installation is straightforward for anyone with basic mechanical skills. It involves disconnecting the battery, locating the old ECM in the engine bay, swapping the electrical connectors, and bolting the new unit in place. However, we always recommend professional installation if you are not comfortable performing the repair yourself.
