Bumper to Bumper Radio, the car guys on KTAR, 92.3 FM in Phoenix, AZ, broadcast every Saturday from 11:00 am to noon. On this show, Dave Riccio of Tri-City Transmission in Tempe, AZ talks about how “tune ups” have evolved throughout the years and what maintenance services you should never skip out on. Also on this show:

• What checks and services are commonly included in a tune up?
• Spark plugs and other parts in your vehicle that will wear out regardless of how you drive and service your vehicle.
• How the tune up has evolved into more of a cleaning service for your car now that modern vehicles are constantly checking components automatically.
• Information about carbon buildup and valve adjustments.
• How your transmission can be affected by a bad battery and why your next battery should be an Interstate.
• 1997 Ford Explorer: After replacing the engine in this vehicle, the crank is no longer turning. Where should we begin diagnosing this issue?
• 2005 Scion: Between 60-70 mph, I’m hearing a whistling sound near my front right tire. What could be causing this?
• 2005 Nissan Pathfinder: What information can you give me about how timing belts relate to vibrations or clicking sounds?
• 2013 Honda Civic: While idling, my AC doesn’t blow as cold. Does this need a recharge or is there another underlying issue?

Cars talked about on this show are the 1997 Ford Explorer, 2005 Scion, 2005 Nissan Pathfinder, and the 2013 Honda Civic.
