So my car is running perfect yesterday....I get in today the Service light is on just when I start up the car....
It shows no symptons and drives like it normally does....
Any ideas before I get the OBD scanner on it?

So a vacuum leak possibly.

My guess was a popped sensor.

Like a CPS? Your car would be running like ass if it was exhaust or intake CPS....
O2? Maybe....

I was thinking an 02 sensor possibly too.
I mean, if your car is fine when you turn it off, then next morning turn it on and it pops on....I just figure maybe the startup popped something or burnt a sensor out....out I could just be an idiot and be in the totally wrong bus.

Maybe O2.
I had codes for a while. If one is going bad, it will pop and clear. Car will drive fine. Maybe slight change in fuel economy.

So an 02 sensor isn't something I should be freaking out about?
I'm gonna get it fixed asap, I just was wondering if that were the problem, how long can it go like this.

I'm guessing you have a cracked intake boot. Mine came on last week and it was and has been driving normally. I did not notice any difference in performance or general running after the light came on.
An old O2 sensor will give you crappy gas mileage and will make your car run bad after a long time.

My car is having horrible gas mileage now....
