So my issue with this car is that it runs and drives but there is no power. We are talking 15mph and or less. Pedal completely to the floor. But I had noticed a vacuum leak underneath reservoir that go's into sub frame.Driver side fender /frame. I need to know what it connects too and if that would be a reason why no power and bafflied exhaust noise. Hesitation in the motor as well. And sorry I am knew to this Forum and Thank you.
