I'd agree with me....er I mean Mark. Let'* see what the code is, and we'll go from there.

Ok well I'll let everyone know whats up with the check engine light as soon as I find something out.

UPDATE:

So I took it in this morning and it pulled code P0128 which has something to do with the cooling/thermostat. After checking a few things out the mechanic realized I had no antifreeze in the resivor and barely any in the radiator. Well he filled it up and told me to keep an eye on it and if it disappears again, that he will pressure test the system. I haven't seen any puddles under the car so I have no clue where it went.

Check the oil level now please.

Then start it up and look at the exhaust... smell odd? look odd? You might have bad LIM gaskets if you aren't seeing any puddling.

Unless your car recently overheated and boiled the coolant away, the coolant is leaking and will disappear again.

WARNING.....billboost'* advice above should be taken IMMEDIATELY. Drive the car for a couple minutes, then check the oil on the dipstick. Does it look normal? Now remove the cap for the oil fill. See any 'chocolate milk'?

Your LIM gaskets are failing and you are combusting your coolant. These are VERY high odds.

If this is true, fix it ASAP before coolant mixes with the oil and destroys your internals. You need aluminum framed LIM gaskets from GM or INTENSE, and GET RID OF THE DEXCOOL. I'ts what destroys the plastic OEM gaskets.

No my car has not overheated, heck, it rarely reaches 200 degrees.

And Boosty and Willwren, My car is parked and I'm at work. When I go for lunch I will check my oil, I'm just running down a block to Burger King, and then coming abck so when I get back I will check the oil.

I would caution you from even starting the car, nevermind drive it. There is LARGE potential for motor siezing here!!!

Well willwren says drive it for a couple minutes and then check the oil, so that'* what I'll do.

Question though...can this be part of my odd oil pressure readings also? I know you all said its fine, but still...

Agreed...not sure where the other Bill is going with run it for a while. If the oil level looks high, then water is in the oil pan. If not.. I'm pretty sure you are burning coolant at a darn fast clip.

Either way. I'm worried and it'* not my car.
