The check engine light is on, but goes off when I accellerate. Could this be the intake sensor? I replaced my factory intake to a Mass AirFlow intake. I also Tried replacing the Oxygen Sensor, but no luck. still on. Any ideas???

Go to the Zone and let them give you a read out of the codes. It sounds like a vacuum leak or the fuel cap gasket may be bad.

Autozone doesn't have the older diagnostic reader. I think it might be the air temperature sensor. Had to unplug it to install the intake. Not sure though. I just don't understand why it goes off when I hit the gas.

Get a Hayne or Chilton manual, it should tell you how to jump wire for self-diagnostic and look up the code in the book. Hope this help!
