Is Your 2004 Durango Running Rough? It Could Be the Engine Computer.
If your 2004 Dodge Durango with the 4.7L V8 is experiencing frustrating issues like a persistent check engine light, stalling, rough idling, or a complete no-start condition, the root cause is often a failing Engine Control Module (ECM). The ECM is the brain of your vehicle, controlling everything from fuel mixture and spark timing to transmission shifts. When it starts to fail, it can create a cascade of problems that are difficult to diagnose and can leave you stranded. Don’t let a faulty computer keep your reliable SUV off the road. This direct-fit replacement is the solution you need to restore your Durango’s performance and dependability.
From the Diagnostic Bay
We had a 2004 Durango 4.7L towed in that was a real head-scratcher. The owner had replaced the spark plugs, ignition coils, and even the fuel pump, but it still had a terrible intermittent misfire and would stall at random stoplights. The check engine light would come on and off, throwing conflicting codes. After hours of chasing wires and testing sensors, we hooked up our scope to the injector control circuits. We saw a clear drop-out on cylinder 3, but only when the engine bay was hot. A quick thermal test on the ECM confirmed our suspicion: the internal driver for that injector was failing under heat. We installed one of these pre-programmed units, and the Durango ran like it just rolled off the factory floor. It’s a classic example of how a failing 2004 Durango Engine Computer can mimic a dozen other problems.
