Ron Ananian, The Car Doctor, opens the hour continuing the conversation about fuel economy and why modern vehicles can lose efficiency long before a check engine light ever comes on. With Memorial Day and summer travel season approaching, Ron explains how issues with fuel trims, EVAP monitors, thermostats, wheel speed sensors, batteries, and basic maintenance can quietly affect fuel mileage and vehicle reliability. He also reminds listeners why now is the time to inspect tire pressure, batteries, fluid levels, and wiper blades before getting stranded roadside during holiday travel.

Later in the hour, Ron helps a Toyota Tacoma owner work through an intermittent misfire problem by explaining how modern computers actually detect misfires and why live scan tool data is critical for proper diagnosis. Another caller describes a rough-running Chevy Sonic with a long-ignored check engine light, leading to a conversation about how vehicles adapt around existing faults and why delayed repairs can create additional hidden problems. Ron also helps a repair shop owner diagnose a difficult Chevy Traverse no-start condition involving CAN bus communication faults, module diagnostics, and theft deterrent issues in modern vehicles.

Ron wraps up the hour with a warning about a General Motors brake fluid recall involving certain AC Delco DOT 3 brake fluid products and reminds listeners to check affected part numbers before summer driving season gets underway.
