Emissions light just came on

[thestilt]

I've had my expy for about 7 weeks and all has been great but the emissions light came on recently.

No noticeable change in how the vehicle runs, no major change in MPG (12 in town 16 on highway).

Still rough on idle when in drive but it has improved after I ran some fuel cleaner through the system. I'm hoping it might be the gas cap (wishful thinking?) but had a quick look around the interweb and cam phasers/catalytics seem more probable.

Will get the codes when I swing by autozone later.

I wasn't able to swing by autozone, may have to wait until after Christmas but will get them when I can.
