Yes the check engine light is on and won't go off. When I drive and the car gets hot or like when the heat is on heating th engine or the whole car when it changes gears I jerks. I can put the car in reverse park whatever it jerks. I forgotthe code but the lady who woks at Pep boys ran the caode and said it was an emission selenoid never said which one.I need to know what it its how much the repairs bcuz its irritating and I hate looking at check engine lights on my car especially not knowing wht it is
