Is your 2004 Dodge Durango suffering from frustrating issues like a persistent check engine light, stalling, rough idling, or even a no-start condition?

This professionally programmed ECM is the definitive, hassle-free solution to get your vehicle running smoothly and efficiently again, restoring the performance and peace of mind you depend on.
Common Symptoms & Your Solution
A failing ECM can cause a wide range of confusing problems. If you’re experiencing any of the following, this part is your answer:

- Engine Performance Issues: Unexplained stalling, rough running, hesitation during acceleration, or poor fuel economy.
- Starting Problems: The engine cranks but won’t start, or it starts intermittently.
