Is Your Grand Cherokee Stalling, Running Rough, or Not Starting?
If you’re dealing with frustrating engine problems in your 2005 or 2006 Jeep Grand Cherokee 3.7L 4×4, a faulty Engine Control Module (ECM) is a very common cause. I’ve seen it hundreds of times in the shop: a vehicle comes in with a laundry list of confusing symptomsโfrom random stalling and poor fuel economy to a persistent check engine light that just won’t go away. These issues can make your reliable Jeep feel unpredictable and unsafe. This isn’t just an inconvenience; it’s a critical failure that needs a dependable solution.
A Technician’s Real-World Experience
“A customer’s ’06 Grand Cherokee came in last week with these exact symptoms. It was stalling intermittently at stoplights and had a check engine light for multiple sensor circuits. The owner had already replaced the crank and cam sensors with no luck. After confirming solid power and ground to the ECM connectors in the RH rear of the engine bay, we knew the module itself was the culprit. A failing internal processor was causing false codes and erratic engine behavior. Installing one of our pre-programmed units resolved all the issues in under 30 minutes.”
