From the Technician’s Bench: A customer once brought in their ’96 LeSabre after replacing three different sensors trying to fix a persistent stalling issue. The car’s computer wasn’t providing clear error codes, leading to frustrating guesswork. After a quick diagnostic, we identified the root cause: the original PCM was failing intermittently. Installing a properly programmed 1996 GM 3.8L PCM 16211539 didn’t just fix the stallโit also improved the car’s throttle response and shifting smoothness, making it feel years younger. It’s a reminder that sometimes the core problem lies with the brain, not the sensors.
