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 to properly diagnose a problem with your car when there is no error code. Also on this show:

  • Common error codes you may read from your car or truck.
  • Where to take your vehicle to properly diagnose an issue and what your shop should do.
  • How air flow in your engine will affect your car’s performance.
  • Systems that aren’t monitored by a computer in your car or truck.
  • 2000 Ford Ranger: My truck will intermittently flash the overdrive light. What does this mean?
  • 2008 Toyota Sienna: My dealership recently changed out my actuators. I was charged $1k. Does that seem like a fair price and was this the cause of my initial problem?
  • 2004 Chevrolet Trailblazer: I have a disc stuck in my sound system. Is there somewhere in town who services these?
  • 2015 Ford F150: My AC light came on, and I’ve been quoted a high price just to have the dealership look under the dash. Does this quote seem reasonable?
  • 2003 Chevrolet Tracker: The brakes in my vehicle lock up while I’m idling at a stop. What could be causing this?
  • 2011 Dodge Ram 1500: At low RPM, my truck begins to vibrate. There are no warning lights on or codes, and no one can seem to diagnose the problem. Any advice?
  • 2011 GMC: I’ve been hearing a high pitch squeal coming from my engine during the hotter temperatures. Have you seen this problem before?

Cars talked about on this show are the 2000 Ford Ranger, 2008 Toyota Sienna, 2004 Chevrolet Trailblazer, 2015 Ford F150, 2011 Dodge Ram 1500, and the 2011 GMC.
