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 the ways you can avoid your car from breaking down and what to do if a breakdown happens, especially during a road trip. Also on this show:

• Things you should always have in your car before taking a long drive in the summer.
• Why you can’t always trust your gas gauge.
• 1997 Ford F350: The batteries at my local shop had been on the shelf for close to a year. Would you recommend purchasing a battery that’s been sitting for that long?
• 1994 Nissan Pickup: I’ve noticed a vibration around 60mph, but never above or below. Could this be a driveshaft issue? Where would you recommend I have this looked at?
• 2004 Mercury Grand Marquis: Are there any AZ citation traffic laws you disagree with?
• 2001 Ford V10: there’s a split in my AC hose. The shops have told me there is no aftermarket part available. Is there someone who could build one for me?
• 2001 Nissan Altima: During an AC repair, my fuel pump went out. After a replacement, I’ve had issues with my fuel line for the past two months – even after other replacements. Is there somewhere else you could recommend I have this looked at?
• 2005 Buck Rendezvous: My engine light has given the reader up to 10 codes. The dealer has narrowed it down to an issue with the O2 sensor. A couple months later, the light has come back on. What should I do next?
• 2004 Chevrolet Colorado: On occasion, my truck won’t turn over despite having a brand new battery. If I wait around 15 minutes, it always fires right up. Have you seen an issue like this before?
