Take it to autozone or advanced autoparts and have them read the code for you. It's free and will save you a lot of money. When you get the codes, post them here and someone will diagnose it for you.

Light went off for like 10-20 mins after my mechanic fixed it and then it came back on after i shut off the car for like 10 mins and then started it back up it came on. so should i just play around with the cover until its sealed properly?

THis is annoying and it sux cause my car is out of warranty even though it only has 41k miles.

My check engine light comes on only when I drive it hard. From startup the light is off, but when I start to floor it or keep it in a low gear using tiptronic it usually comes on, but i'm taking it to the dealer soon.

it's gonna either be faulty O2 sensors or a faulty mass air flow sensor.
