Expert Pro Tip
Before condemning your ECM, always perform a thorough check of the basics. A weak battery, corroded battery terminals, or a faulty ground strap can mimic ECM failure symptoms. Specifically, check the main engine-to-chassis ground. A poor ground can cause voltage drops and erratic behavior that can easily be misdiagnosed as a bad computer. A few minutes with a multimeter can save you hundreds of dollars.
