Chevy Silverado 1500 with the L3B engine are included in a Service Update with a fix for a fuel injector flow rate problem.

Q: My 2002 Buick LeSabre has 98,887 miles on it. Its ignition control module is failing. Since 2014 I have replaced it three times. Can you please tell why my control module keeps failing?

Have you ever wondered why GM, Ford, and Chrysler converted from distributors to distributorless ignition systems ... GM DIS system and LS powertrain control module (PCM—aka computer).
