I have this problem when i press the gas pedal hard to gain speed on the freeway or anywhere for that matter the engine light and track off light come on it doesnt do it any other time only when i press down on the gas i can go fast sometimes and it not come on but other times it does regardless of the speed i go it comes on when i press on the gas hard enough. Has anyone had this problem before and can help give some advice on how to fix it thanks in advance.
