“The problem that I'm I'm having is a code p0456 (evaporative emission system leak detected, which is a small leak. The reason why I'm worried is because the gauge for the rpms goes all the way across as far as it can go, in other words it's like as if I'm pushing down on the gas pedal as far as it can go , it does this when I'm driving on the highway, when I'm about to leave a signal light from a complete stop , when I'm driving up a hill is when it's worst.”
