Gas Cap vs Chk Eng Lite

I have a small leak in my down pipe after hitting a rock, When im stuck in
the traffic for too long the sensor will detect the small leak and will give
me check engine and then the GC is running terrible. I disconnect the
battery for 10 Sec and tada the light dissapear. The code might stay log in
the computer but it's running ok and not worse or better on gas then before.
