I'm a newby to the posts...sorry to offend, by my post title...but I am desperate.

It's a NON turbo...It does not blow any smoke...Let me try to be more clear.
At the mass flow sensor...minimal air is sucking in. Tested another 740 non turbo and it humms like a vaccume cleaner.

When I hit the gas...not a lot of exhaust is blowing out the tail pipe.
And on deceleration...it is sucking into the pipe.

I have cleared the exhaust line...and found no blockage there.

I have cleared the intake manifold and found no blockage there either.

I was looking for a nest or a shop rag or something foreign.

BUT, the engine itself runs fine...I do however have lack of power.

All circuits check out fine with electronic diagnotic tools...Even check the valves for clearance and only 1 was a little tight...repaired that.

I appreciate your help...I know it sounds like a simple vaccume leak,
but it is nowhere to be found.
