Engine Performance problem
2002 Chevy Trailblazer 6 cylinder Four Wheel Drive Automatic 84000 miles
How do I replace the ECM? I am not even sure where it is. What do I replace it with? I have seen where I can buy reprogrammed ECM' s. But I have also been told I have to have it programmed after install. Thanks in advance.
