Review on GM Genuine Parts Ignition πŸ”Œ Coil Interface Module - Model D1977A by David Skyline

Revainrating 4 out of 5

AC Delco part is worth the extra money

If you have a mid-size GM car from the early 2000's and need an ignition control module, spend the extra money on a Delco AC module. Seven modules from another manufacturer were installed in the garage in eight months. Eventually I insisted they use the Delco AC part and the problem went away.

Pros
  • Decent performance
Cons
  • There are downsides
