blow by hose?

Still trying to figure out what is wrong with my car. The FSM mentions pinching the blow by hose in some of the diagnostics. What is this?? The picture in the manual doesn't look like anything I can see in there.

i think you're refering to the pcv hose that carrys engine blow by back through the pcv valve to the intake manifold but i could be wrong.

I don't have it in front of me for the page number, but it was in the diagnostics for low power and the next page for detonation. It said to pinch the blowby hose and showed a picture of 2 boxes with a short 90degree elbow hose between them.
