Re: running rough

Before I suggest anything else, I need to be clear.

Do you mean when at idle and in drive when you step on it, it is snappy, or do you mean when at idle and in park (or neutral) and you step on it, it is snappy?

If you are connected to manifold vacuum this makes sense, manifold vacuum falls off at the throttle is opened, where as ported vacuum will come up as the throttle is opened.
