Is your trusty 1997 GM truck, van, or SUV suddenly unreliable?
Stalling at stoplights, struggling to start, or a persistent Check Engine Light can turn your dependable workhorse into a source of constant frustration. You rely on your vehicle to get the job done, and when its brain—the Powertrain Control Module (PCM)—starts to fail, it can feel like you’re chasing a ghost in the machine. Don’t replace your trusted vehicle; restore its core reliability with a solution designed for a perfect, hassle-free fit.

- Unexplained stalling or cutting out while driving.
- Harsh or erratic automatic transmission shifting.
- Complete no-start condition where the engine cranks but won’t fire up.
- Noticeable decrease in fuel economy and overall performance.
