When your check engine light comes on, don't ignore it thinking it's something minor like a loose gas cap. It could very well be something more serious like a shorted or corroded ECM for Chevy Trailblazer, especially if you're experiencing poor performance. Get a fault code from a professional or use a voltmeter to determine if you need to order a new ECM from AutoZone. We offer the right products at the right prices as well as home shipping.
