Had the same issue, odd power loss, was like driving N/A.
Turns out it was a small piece of vacuum hose at the bottom of the brass colored pipe leading from the MAP sensor to the to of the intake manifold.
Trouble is you won’t find it unless you take the EGR assembly off and the upper part of the intake manifold.
Just follow the MAP sensor all the way to the block. It’s MAP sensor, vacuum hose, brass pipe, vacuum hose, manifold.
It’s basically a 20 cent piece of hose in the depths of hell..!!!
