Special guest includes Mesa Auto Works. Also on this show:

• What is eco-boost?
• What is direct fuel injection?
• What is turbo charging?
• 2006 Toyota Corolla: I bought a tire about six years ago and recently had it put on the rear of my car. The tire ended up coming apart and causing a lot of damage to the car from the tread. Is there a shelf life for tires?
• Toyota Sienna: I'm considering buying a Sienna but am not sure what the difference is with all of the acronyms such as EX, LX or LE series? 
• Dodge Ram 1500: Do you think the coil springs on the Dodge Ram makes the truck run more smoothly?
• 2007 Dodge Ram: Recently the air conditioning has been blowing warm. I was told to buy a product that I could pour into the system and it would seal up any leaks. Does this work?

• 2005 Toyota Sienna 80,000 miles: When I coast to a stop, the vehicle wants to drop down a gear.
