It was hauled into the shop on flatbed but it drove back from the shop. And I checked the vacuum line and it was connected at both ends. At the trans and intake manifold. And it is a brand new hose the shop put it on. Is it possible the engine isn't making vacuum or not enough? And if so how would I check that. I don't have a vacuum gauge on the truck.
