Service Engine Soon/Gas Cap

I gased up yesterday and got the infamous "Service Engine Soon" light.... Will this reset if the gas cap is reset, or do I need to take it to a service rep to have it turned off?

BTW, I have a 2004 Spyder GTS...

Thanks.

Yep, if you just drive the car for a good few miles, the light will go off. If it doesn't, then you've got another underlying problem.

Okay then. Well, I have a 25 mile ride home today. So I'll give it a whirl and see how long it takes to turn off--if at all. I'll let you know what happens.

Thanks
