1k rpm rattle

Whenever the rpms go thru 1k accelerating or decelerating, something make a rattling noise and you can feel the engine lag for a split second. Rats nest has been removed, shttuer valve has been removed, have cruise control and ac still hooked up. Any Ideas?

Mine did that when I had a vacuum leak, replaced the hose and it was fine.

"It will be the last one you check" ( Murphy's Law of Vacuum Line Selection )

If you can't find it, set your idle at 1050 and ta-da !!!
