This module is a bonus presentation from the IATN Convention in Detroit (2001), covering how to leverage the IATN fixed database as a diagnostic resource. Tom walks through the search process and uses real-world case studies to show how archived tech mail solutions can point you toward a diagnosis you might not have considered on your own.

Cases covered include:

• A 96 Ford Escort with an intermittent misfire on cylinders 1 and/or 4, traced to dropping valve seats
• A 90 Buick Park Avenue 3.8 with a rolling miss on cylinder 5, caused by a rough roller lifter

The takeaway is how searching the IATN archives can shift your diagnostic mindset and save significant time on elusive, hard-to-duplicate problems.
