I've been having issues with the way the car drives at a constant speed. When I accelerate, this car gets up and goes. But when I'm at a cruise, I can feel a little bit of pulling. I just can't pin point where it is. I'm wondering if it is in the gears. Another thing is,in nuetral, when the clutch is depressed, I've got pervect idle. When I let it out I can hear a bearing spin, then the motor starts surging. Any suggestions for any of it?
