Ours is broke. Got a exhaust leak sound (previoud thread) Anyway with it leaking does it cause a loss of power? When you really kick the 302 in the pants at around 4000 the tack starts jumping up and down and the motor seems to miss. I am talking about flooring it to move in a hurry. This is not on a constant basis. Just noticed it last night. First time I have ever done that. Just looking for ideas.
