When the light first came on (way back when) it was after a quick road trip with 5+ hours of driving on each of 2 weekend days – a lot of stress for any vehicle.  So I didn’t get too worried and – lo and behold – it went off again within a couple of weeks.

It came on again after a different road trip and this time I had it checked out, since we were so near the drive back to Seattle.  "New spark plug wires" was the necessary fix, and the light went dark once again.

That brings us to Vantage, WA (nearly home) when the light comes on again.  "It just does that on long trips – it’ll turn back off after we’re home for a little bit."  And after a couple of weeks, off it went once again.

In the past week it has lit up and turned off at least 3 different times.  I try to tell my truck that it has to decide – if something is wrong, then come on and stay on, or maybe don’t start or run weird or something… give me a clue.  But if all is well then no lighting up – or else it will be known as the truck who cried "Check Engine!"
