Check Engine Light

The check engine light come on every now and again seemingly without any reason. If may come on a couple of times for 3-4 sec during a 15 min trip and then will not be seen for the next 3 days.
Can anyone suggest what I should be checking?

Check what the engine code gives

How-To for checking engine codes here.

I'd bet on it being an O2 sensor. Mine has done that frequently. I'll get around to it eventually.

The last CEL I had like that was the knock sensor. Luckily it was the front one that was easy to get to w/o taking anything off the motor.
