Contrary to what I thought was the vacuum hose on my previous post (labelled as red) that turned out to be a water hose and is connected. This hose is further back under the throttle body (about 2 inches further back) and is much slimmer, but is definitely an air vacuum hose, again in the 6 o'clock position like the water hose at the front. For the life of me I cannot see where this connects.
Somebody must know where this hose connects and I would appreciate some feedback.
are you talking about this one, that ive circled ?
im not familiar with the vacuum layout on that engine, and cant find any decent pictures or schematics, to see where the pipe goes, or what it does.
i can only suggest, to jack the car up, and have a look from underneath, with a bright torch.
if the pipe is torn, like you say, then the other half of it, should be dangling somewhere, not far away, or if the hose has left the building, there will be a bare pipe end visible somewhere.
if youve looked and looked, around the whole engine, and cant find anything, you can just twist a tightly fitting bolt into the hose, and secure it with a jubilee clip or cable tie, to plug it up. temporary fix.
that will fix the air leak at least, and make the car driveable for now, untill youve found its location.
check all the stuff, that can potentially run from a vacuum, like crankcase breathers, fuel evap tanks, brake boost lines, idle control valve, map sensor, pressure control valves, etc, all that stuff. you will stumble across a broken hose, or pipe end, sooner or later.
