Intermittent Check Engine Light: If the check engine light on your 2007 Tahoe is intermittent, try to take note of the conditions when this happens. For example, does it happen when you accelerating, driving on the highway or does it appear at low speeds? This will help your mechanic evaluate the issue. Steady Check Engine Light: If your check engine light is on every time you operate your Tahoe, you need to have it checked as soon as possible, especially if you notice performance problems or unusual noises. Flashing Check Engine Light: If your check engine light is flashing, stop driving your Tahoe and have it towed to your nearest mechanic - you probably have a very serious problem with your car and you risk ruining your engine by driving it. If you are unsure about what your diagnostic trouble codes mean; have your Tahoe diagnosed by a professional automotive technician.
