What about it?

In addition to redline's answer, you should drive the car in both highway and city type traffic for that 50-100 miles. The engine needs to be at normal operating temp during the drive and it can be done in stages or all in one trip.

the "drive cycle" is anywhere from 25-125 miles after a "reset" has occurred . (usually 75 in my experience)
this is the period where the ECU learns things, and runs its diagnostics. expect better gas mileage after this period usually.

Take it to autozone or another place like it and have them read the codes and tell us what they are.

its not the computer

After tightening the gas cap, you will have to drive the car a few 'cycles' before the light goes off. If that doesn't work, have the trouble codes read to find out exactly what is wrong and causing the light to illuminate.

Hi, I believe their is a TSB for your model. You'll want to check with the dealer because if the ECM needs replacement it should be covered under the emissions warranty. More info @ P0607
