Service light came on and book says emissions or fuel cap. the car seems to be running fine. Is there something else I should check
The quickest way to determine the cause is to visit a local parts store, of a major chain such as Autozone, etc. most of these offer a free computer scan that will reveal the source of the engine light. In the mean time, try refueling with a full tank of fresh fuel from a different source than you used the last time. sometimes water or other fuel problems can cause the light to come on.
And yes the loose fuel cap may cause the light. If you have more than 60,000 miles on your car, it may require some tune up parts such as oxygen sensors and such. CHECK YOUR WARRANTY!!! most states require the manufacturer to replace the emission related parts at mileages of 100,000 or even 150,000 so dont buy something you could get for free!
I had the same problem with my G35 05 after i forgot to close the cap, Usually the car will run for about 100 miles or so before the light goes away, but you can also, reset the ECU by checking this site http://www.6mt.net/forum/performance-mods/2833-easy-ecu-reset-procedures.html
Or what i did was pulling the fuses marked "Eng cont/inj, there is a 15A under the hood, in the fusebox near the battery, and a 10A in the driver-side interior fusebox - pull both. (As someone suggested in the same thread)it worked.
Same happen to me, when this happen i took it to chevron techron and added some fuel system cleaner by stp
On these newer cars that code will come up when you get gas, and dont tighten the cap back tight enough. try taking the cap back off and put it back on more than 5 clicks and drive the car for awhile. if this does not clear the check engine light take it to a auto parts store and have them run a scan and erase the code( normally they will do this for free)
