Hi. I have a 2006 Jetta 2.5 with 73,000 miles on it. The engine light came on, and it idles too low, and then if you touch the gas pedal it will rev up to around 3,000, and back to 800, and back and forth constantly. It has a manual transmisson, and even when I try and drive it it'll rev high when I depress the clutch pedal to shift. I remember the engine light came on about 6 months ago, and the dealership indicated that something (which I cannot remember) was possibly getting ready to go.... Any ideas on this one? Of course it's Sunday od Labor Day weekend, and I am stuck. I won't drive it as it is.

The "check engine" or "Service Engine Soon" light is an indicator for a system that monitors many electronic functions in the system, also called the "malfunction indicator lamp" (MIL). It can come on for any of hundreds of different causes from any of the systems that the computer monitors. Some are very important and can lead to further component or engine damage and some are emissions related not as serious but still a problem and need to be repaired.
Your first step is to have the computer scanned to retrieve the trouble codes that were set when the check engine light came on. Those codes will give you specific information about what the computer saw and will get you pointed in the right direction to find your problem. With a 1996 or newer and some 95 cars and you have an AutoZone or Advanced auto parts in your area, they will read them for free. Once you have these code numbers, we can be a lot more specific about what your problem may be.
