it was idle bad at all and i payed out of pocket, it was just a normal idle then it broke down took it in to get it fixed saying it had a rough idle and they had to detune it to see what it was and i explained my tune would have anything to do with it since its been that way for 2 years. when it drives its fine i get on it goes without any problem but when im stopped shit either goes from 1.5 to basically 100 and back idk whats wrong ill clean my throttle body today would it be the air filter or spark plugs maybe?
