Im a new member, so thanks in advance to anyone taking the time to reply, much apreciated !!

Well, honestly, the first thing you should look at is "What was the last thing done to the car before the CEL came on?"

If you just had the spark plugs changed a couple weeks ago, then I start by pulling off the coil sticks, checking to make sure the spark plugs are properly torqued down, and then making sure the coil stick snap into place.

If the CEL comes on again after that, pull the codes, and let us know what they actually are.

I've read what Frodo says too... that if the CEL light is flashing, it's something that warrants you not driving the car anymore until you can get it looked at. If it is a solid light that doesn't go out, then you can continue driving it for a while, and get the codes read to see what the issue is.

You should get the code read (either buy a code reader at an autoparts store, or bring your car to a shop where they can be read). Once you get the codes, you can then determine what might be the problem. Good luck.
