🚨 Is your ECM causing misfires? We’re working on a Caterpillar 3126 ECM today. 🔧The customer replaced injector 6 and harness, but it's still misfiring. After testing, we confirmed the ECM is the problem. 🛠️Inside, we found poor soldering on several pins, which caused the issue. ⚡💡 Tip: Always test your ECM before and after repair to make sure it’s working 100%.Got ECM issues?
