You should go to a dealer and get the error codes read. The Engine light in your car is for OBDII, or on board diagnostics next generation, hence the II. This light is on due to a problem with your emissions system. A few simple solutions is to make sure your gas cap is firmly closed, and that it actually fits, or if you just changed the type of gas you normally use, go back to that brand. Different brands, differnet types of refinement, octane etc etc... There are a few serious problems along with your check engine light. A few examples are as follows. 1. O2 sensor is not functioning 2. EGR valve is not functioning. 3. You could be having a misfire (your CEL would be flashing at this point) These are just examples. Take it to a dealer to be sure. Anyone can clear a code, but in the long run, the light will come on again, and you will still have an undiagnosed problem. hope this gets you going in the right direction. Chris
