Sorry, I can't help but I can sympathize. Sounds like I have the same thing. Does it happen all the time? Is it when you are idling or when you are accerating too?

 

have you done a compression test? the 3VZE is notorious for burning #6 (thx to toyota's wonderful crossover design)

 

Yeah, try compression testing it. Also, you might have a vacuum hose loose or something. I was cleaning out my throttle body one time and a hose came loose that I didn't see. Started the rig up and sounded like it was missing. After a long search, I discovered that a vacuum hose had come loose right under the throttle body. Re-attatched it and it ran like new.
