My check engine light is coming on, only when i accelerate ( when the pedal is close to the floor). Any suggestions on what may be causing this? Once i thought that the car filled up with gas fumes, but I was in traffic and i thought maybe it was the cars around me, the fumes haven't happened again since that, but the engine light is still doing the same thing? Help? Please.
