The attached handy Pocket Guide(s) are being sent to GM dealerships to assist them with quick diagnostics and repair of passenger car driveability conditions.
This was deemed desirable due to the volume of service bulletins and information published on driveability and due to the changes in engine design and diagnostics over the past few years.
Four Pocket Guides will be provided to each dealership for use by the driveability technicians. They summarize all information into a "condition, cause, and correction" format specific to resolution and the "do's and don'ts" for each model year engine.
All Service Bulletin numbers are current and correct as of April 20, 1990, but are subject to change. This Pocket Guide may not be updated to include future bulletins.
