So you come out to start your car one morning and the Check Engine light on the dashboard comes on…and doesn’t go back off again. You can’t really notice any difference in the way the car runs and drives, but it’s on anyway.
What does it mean?
Since the late 80s, most engine functions have been controlled by a central drivetrain computer. This includes emissions controls, fuel metering and delivery, ignition timing, shift points and many other elements of drivability and performance. The drivetrain computer relies on information from a chain of sensors that monitor exhaust composition, camshaft position, throttle position and many other factors.
The voltage readings from any of these sensors are supposed to fall within a certain range. When ...[more]

The temperatures are inching upward, the days are getting longer and the first buds are starting to appear on the trees. Spring is on its way, and soon it’s going to be time to do a little preventive maintenance on your ride. No need to dread it -- it’s all pretty routine stuff!

Nobody likes driving around in a hot, stuffy car, and a car with an AC system which only works marginally is somehow almost even worse than one which doesn’t work at all. Let’s go through a few tips which can help you keep your ride a little more comfortable this summer…
Remember a cars AC system is really a heat exchanger which moves hot air out of your vehicle, then replaces it with cold air. One thing you can do to help improve its efficiency is to leave your windows down an inch or two (if possible) when you park the car, helping to prevent excess heat buildup. When you start the car and begin to drive off, lower all the windows for the first minute or two to help move hot air out of the car more quickly, giving the AC system a chanc ...[more]
