Light came on just now... Not sure why. No messages on the DIC... Temp gauge is normal. Gonna try resetting pcm I guess and see if it clears....

Don't just reset it. Just turning off the light doesn't help you troubleshoot. Any of the chain parts stores will read it for you.

If yours hasn't had the head job yet..chances are this is what is throwing a code P0300 (random misfire on one or more cylinders) for the CEL to come on...Mine was on cylinder #4 and my code was P0304.

If the last 6 digits of your VIN is below 287591, then it is one of the bastard children engines with bad intake valve seats.

But Maybe not, maybe something as simple as a loose gas cap.

It must've been the gas cap... That's the first thing I checked. It's out now so I'll be keepin an eye on it... Service records say the head was replaced at around 35,000mi...
