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.

Ron Ananian, The Car Doctor - May 9, 2026 -  Hour 2 - The Problems Your Car Isn’t Warning You About

https://api.omny.fm/orgs/e73c998e-6e60-432f-8610-ae210140c5b1/clips/6056dce7-8caf-4bda-b587-b4450157a522/transcript

Ron Ananian, The Car Doctor, starts the hour talking about rising fuel prices and why the real problem for most drivers may actually be fuel waste caused by overlooked maintenance issues. Ron explains how low tire pressure, dragging brakes, dirty air filters, weak batteries, and lazy oxygen sensors slowly rob vehicles of fuel economy long before a warning light ever appears on the dashboard. He also revisits the old-school “clothespin on the fuel line” trick and explains the vapor lock theory behind it.

Later in the hour, Ron talks with a listener considering the purchase of a late-model Chevy Suburban Duramax with a branded title and discusses the risks involved when buying a vehicle with a complicated repair history. Another caller reports back on a difficult Nissan Murano misfire diagnosis that ultimately turned out to be three failed ignition coils on the same bank of the engine — a repair almost nobody would expect. Ron also helps a longtime Ford Escape owner decide what modern SUV might replace his trusted 235,000-mile daily driver.

It’s another hour of practical diagnostics, real-world repair stories, and common-sense automotive insight from Ron Ananian, The Car Doctor.

Ron Ananian, The Car Doctor - May 9, 2026 - Hour 1 - Why Your Car Is Quietly Burning More Gas

https://api.omny.fm/orgs/e73c998e-6e60-432f-8610-ae210140c5b1/clips/bc51f64f-ed93-4451-9181-b4450157108e/transcript

Cheap Gas, Sensor Failures & The Truth About Modern Motor Oil

From the archives — September 19, 2015 (Hour 2).

Ron opens the hour with a timely discussion on falling gas prices—and what “cheap gas” really means for your vehicle. Is lower cost fuel always a good thing, or is there more to the story?

Listener calls bring real-world problems to the table, including a 2007 Nissan Sentra with a failing cam position sensor causing hard starts and rough running, and a Chrysler PT Cruiser experiencing electrical gremlins after an ignition switch replacement—affecting both the radio and instrument cluster.

Ron is also joined by Ray Bogers, General Manager of Lubricants Technology at Pennzoil, for a conversation about evolving motor oil formulations, new standards, and what today’s engines really require for proper protection.

The hour wraps up with Ron revisiting and clarifying a few lingering issues from the previous program—bringing added insight and closure to earlier discussions.

Insightful, practical, and always focused on helping you make better decisions about your car
