hey guys,

started my car after it had been sitting for a few days and it barely turns over. When it does, I hear this rumbling noise and the car is shaking violently and the smoke smells awful. This hasn't happened since, but I think that the acceleration isn't as good.

I think it's a spark plug, but I could be wrong.

oil seperator valve on the back of the intake manifold (leak), clogged fuel filters, vacumn leak.........................:dunno
