check engine light twice within a week of purchase??

First, make sure your gas cap is on real tight (you should hear it click). If the cap isn't tight enough, the engine light can come on.

Otherwise, what Forest said.

Take it to the dealership. I've been taking mine for a year and the check engine light was on. They never asked me about it cause my car has some mods (intake header, 2"exhaust with 1 cat, 1.8TB, pulley, etc.). One day I asked them to scan the car and it was my Gas Pump (Gas pump malfunction and lines deformity). The warranty covered it. So take it back.
