An Expert’s Note on Late-90s GM Computers: The PCM in these 1997 vehicles, like the venerable 3800 V6-powered cars, was a workhorse. However, after 25+ years of heat cycles and vibration, the internal circuit boards and solder joints can develop microscopic cracks. This leads to the maddening intermittent problems you’re likely facing—issues that appear and disappear with temperature changes or road bumps. Replacing the entire unit with a solid, tested module like this one isn’t just a repair; it’s a foundational fix for your vehicle’s reliability.
