Probably a dirty MAF. Clean it and the air filter.

Mass air flow sensor. The sensor on the intake tube between the intake tube and air box.

Go get the code pulled for free @ autozone and post it. If you are near me, I can pull it.

Definetly. Just not putting the cap on tight can cause a CEL.

Thats why it son. Just a loose one will cause a CEL, im surprised it didnt come on sooner if it wasnt on for two days.

you need a scan tool to turn it off. run up to autozone again and have then turn it off.

It will turn off on its own as soon as it runs a EVAP test again and passes.

Most times discoing the battery wont clear OBDII codes. Hit up a autozone or something and have them pull the codes. They might clear them if its a EVAP code and you tell them you lost the cap before.
