Where does this go???
I have an 89 Formula with the L98 engine (TBI). Now, I have a thin vacuum hose that runs from underneath the throttle body, back past the EGR valve, that isn't connected to anything. It's just hanging out there.
According to the vacuum hose diagram, it should be running to about the same place as the thin hose that comes out of the EGR itself. The Chilton's from 1989 doesn't have the best diagrams.
The unconnected hose is just long enough to reach as far as the EGR outcoming hose is, but I can't find a place to connect it!
Does anyone else know what I'm talking about? And can this 2mm thick vacuum hose be the cause of my rough idle and overall running crappy???
