Today I was driving and the check engine like came on randomly. I had my car inspected five days ago. I drive a 2003 Ford Focus ZXT.
Any suggestions on how I can troubleshoot the problem?
Thanks,
Start by getting either a mechanic or someone with an OBDII scanner to read the code so you know where to start. Lots of time a loose gas cap will cause a "Evap system small leak" code which illuminates the check engine light for a while. Other than that I can't help you much without knowing what code comes up.

The orange light showing a diagram of the engine remains lit during driving.
When getting inspected, the computer is clear. I have to drive the car for another 50-100 miles and if I don't shut off the car they can read the computer. However, if I shut off the car the computer resets to clear again.
your prob all set just saw this was an old post. I am going thru same thing now on my 06 Focus
